Abstract:The urbanization level and demand of urban land-use in future are forecast on the basis of natural condition, social and economic environment and the present condition of development in Dazu County. In the future, the supply-demand contradiction in urban land will be more intensive with acceleration of urbanization. Therefore, on one hand, urban land in major towns should be increased properly with centralization and land rearrangement of rural settlements;on the other hand, utilization ratio of land should be improved with enhancement of intensive use of urban land. In Dazu County, the demand of urban land should be satisfied primarily in towns with strong economy and urban land use should be increased properly in towns with general economic level but with potential economic development in the future. As for other towns, the urban land-use increase should be controlled.

Abstract:Longgang District is an important industrial park for carving out a business in Shenzhen City. The author thinks that the rural urbanization course of Longgang District is obvious in phases. At present, it is in fast development period. The basic characteristic of the rural urbanization in Longgang District is as follows: 1.The raw and processed materials come from out and the products go out of the district; 2.The urbanization standard of the west of Longgang District is better than that of the east. According to the analysis on economic growth, economic type and industrial structure during different years, the driving force and the differentiation law of urbanization in Longgang District is put forward.

Abstract:Spatial interpolation includes point interpolation and areal interpolation. The point interpolation is mainly used to deal with natural geography data and the areal interpolation is usually used to solve the interpolation problem of social economic statistic data. However, social economic statistic data are often collected by areas, which cannot represent their real spatial distribution. A spatial distribution model of social economic statistic data is to be established to conform to their real spatial distribution. Using the areal weighting interpolation and inverse distance weighted averaging, a spatial distribution model of GDP is established in this paper.

Abstract:The national structural codes GB50010-2002 and GB 50011-2001 have been modified in many aspects compared with the old ones. To verify the effectiveness of structural capacity design provisions in the new codes, firstly, two typical RC frame structures of Grade 2 in intensity-category 8 and Grade 1 in intensity-category 9 are designed according to the new codes. Then, nonlinear dynamic analyses of the two structures are carried out under excitations of several ground motions with the fortification and rare intensity levels. With the analysis results the availability of strong column weak beam is checked carefully, which is desirable with capacity design measures of RC frame in Chinese new structural design code. The conclusions drawn from the analysis are helpful to structural design and local modification of the codes.

Abstract:Coupling beams are the key elements of plastic energy dissipation mechanisms in coupled walls.However,the design of the small span-to-depth ratio coupling beams with high ductility is still one of the problems not solved effectively in domestic and foreign seismic reinforced concrete structure design.The research group,where the authors of this paper are,brings forward a new reinforcement scheme with adding diagonal and rhombic bars to traditional reinforcement in the foundation.Test results prove that it is an effective way to solve the problems for it has good seismic performance and is easy to be constructed.This paper puts great emphasis on introducing the trial results and principal rules that are deduced from the test results of second set of specimens with low reinforcement rate.

Abstract:Different creep coefficients of concrete layers in composite beam will cause redistribution of stress and additional stress in section. Based on the concept of strain compatibility approach, in this paper,the authors deduced a differential equation of the additional inner forces resulted from creep. Thereafter, the authors proposed an equation to calculate stress redistribution of steel and concrete composite beam, concrete composite beam and concrete strengthening member. At last, the formulas of additional stress of the section were proposed.

Abstract:A new reinforcement arrangement scheme was suggested to provide satisfactory seismic performance and good workmanship for the coupling beams with small aspect ratio. Coupling beams with small aspect ratio are counter flexural deep beams with both ends restrained, in which the Bernoulli hypothesis are not valid. Although their load bearing capacity can be predicted with the strut-and-tie model developed recently, how to simulate this kind of beams adopting new reinforcement arrangement is still a problem. A macroscopic strut-and-tie model is thus presented for these coupling beams. Good agreement with experimental results is achieved.

Abstract:In elastic-plastic solution of expansion of spherical cavities, based on Mohr-Coulomb strength criterion, the effect of intermediate principal stress on yield and failure of soil is not analyzed. Therefore, there is disparity between results obtained by Mohr-Coulomb strength criterion and those obtained from experimental data. In this paper, the elastic-plastic solution of expansion of spherical cavities, based on unified strength theory is established and unified solutions are obtained. The corresponding solutions of different materials can be obtained. The unified solution cannot only be used to fit the properties of the materials with different tension-pressure strength, but also those with equal tension-pressure strength. The results show that by this solution, full use of the properties of the materials can be attained to reduce supports, which is of important significance for engineering

Abstract:Application system generally refers to all kinds of computer information system. It aims at improving the sharing and application of the resource. The resource in application system usually means data resource. For computer management and maintenance, there are not only data resource, but also program resource and network resource. Effective management of this resource is key to ensure proper work of the application system. In this paper, the basic pattern and policy for resource management is put forward and a method to build and realize the resource layer that lies between database layer and application layer is to be found. This management layer, which skillfully connects the application system with resource and establishes good base for application and exploitation of system, is named as resource management system.

Abstract:The chemical composition and form of impurities in titanium gypsum and their effects on properties of cement were introduced when used as set retarder for Portland cement. Experimental results show that the impurities are mainly Fe (OH)_3, FeSO_4 and Al(OH)_3, and they may do little effect to Portland cement. The properties of cement with titanium gypsum are similar to those of Portland cement with natural gypsum,

Abstract:In conjunction with the current situation of the real estate market in China, the main influence caused by the credit and loan adjustment policy is analyzed. On this basis, it has proposed some suggestions on how to strengthen the competitiveness and ability to resist risk of the real estate enterprise. At the end, it is emphasized, that the credit and loan adjustment policy not only makes the enterprise under enormous pressure, but provides a great opportunity of reducing rivals and expanding its own scale to those really powerful real estate enterprises. The real estate enterprise should seize this opportunity to meet the challenge to expand and strengthen itself.

Abstract:In this paper the concept and active impaction on economy of timeshare were introduced. According to supply, demand and basic condition, developing timeshare estate were provided with basic condition in China. Analyzing the history of timeshare we can get the conclusion that it was unused real estate to startup the timeshare and so the development of timeshare in China have partly active effect. At last, in this paper the policy risk, consumption anticipation risk, lack of demand risk, product design risk, market orientation risk, system management risk, competition risk, internationalization risk, and market impression risk were analyzed except the market risk, business risk and polity risk and so on which were the common risks of real estate. And the countermeasure and measure how to promoting the development of timeshare estate were put forward.
