Abstract:In this paper, three fundamental principles of city planning under the present system are brought forward: the integration of urban design and city planning, the double attributes and position of the urban design and the correspondence between the urban design and the city planning in levels. Therefore, according to the different circumstances, three functioning ways for the urban design in the practice of plan making are put forward: to put the urban design into the system of city planning, to work out the urban design as a research work and then make use of its achievement in the work of plan making, and to regard the urban design as a specialized work of city planning.

Abstract:The double layer subgrade with rigid upper layer and soft lower layer is common in engineering construction. In this paper, the elastic and elasto-plastic analysis on such subgrade by ANSYS was carried out. According to the calculation results of FEM, the plastic zone of subgrade would appear in the upper layer soil of interface, then, it would be expanded up and down with increase of the load. As for the lower layer soil is relatively soft, the plastic zone is expanding rapidly. Finally, as the plastic zone reaches the bottom and the subgrade in the state of ultimate bearing capacity, the calculation starts to be non-convergent. The results can serve as reference to the engineering designers.

Abstract:The mechanism of shrinkage cracking is discussed with a simple member, which is fully restrained and subjected only to an axial restraining force caused by shrinkage, while a simple procedure is presented for the determination of the number and spacing of the cracks and the average crack width. With the simple model, some examples are shown to compare the provisions for minimum shrinkage and temperature reinforcement in GB 50010-2002 Code, ACI 318-02 Code and AS 3600-1988 Code. The results show that the provisions in GB 50010-2002 Code are too weak in comparison with the others. Finally, some recommendations are proposed.

Abstract:The grading of lightweight aggregate (LA) and its water content has an effect on the plastic shrinkage cracking of lightweight aggregate concrete (LWAC). Test results show that the water absorption of LA and the water evaporation of the concrete increased with the increment of cubage of LA, but the area of plastic shrinkage cracking of LWAC decreased. Besides, LA with high water content is beneficial to restraining the plastic shrinkage cracking of LWAC.

Abstract:In this paper starting with characteristics of real estate industy,the mechanism of fonmation of the real estate economy bubble is explained with real cases,and the regional characteristics are interpreted through analyzing the average sale price of commodity house in cities as Beijing,Tianjin,Shanghai and Hainan province and the whole country from 1987 to 2001.In the end of the paper,the author concluded that the regional characteristics of real estate economy bubble are decided by such characteristics as non-fluidity of the product,diversity,venture capital and market region.So the government should not only inspect and manage macroscopically the economy bubble but also control the regional economy bubble,which will ensure the steady development of the whole industry and prevent the systematic influence on the macro economy resulting from bursting of the regional economy bubble.

Abstract:As far as the urban land structure is mentioned, it means the distribution of urban land among the different industries of the city. The problem of urban land structure is referred as unreasonable allocation of urban land caused by several factors, including the decision making mechanism of old economy and urban development policies. Different from using Fractal theory, Entropy theory and Functional theory, in this paper, with reference to Dissipative Structure Theory, one dynamic, systematic and historical optimization model of Max f(J_i, X_i) with two parameters of J_i and X_i will mainly be set up. This model can be used for analyzing the key factors determining the optimization of urban land structure.
