Abstract:The penetration resistance of jacked pile was calculated by using the specific penetration resistance of single bridge cone penetration test. According to the comparison between estimated bearing capacity from Technical Code for Building Pile Foundation (JGJ 94-2008) and measured value, the calculation method of estimating the penetration resistance of jacked pile was put forward, which took comprehensive correction coefficient α and β of pile tip resistance and skin friction of pile into consideration. Besides, the calculation formula of base resistance and side resistance were also defined. Several suggestions for determination of comprehensive correction coefficient were given for different soil layers. The proposed approach was compiled in the Visual Basic visualization program, and the corresponding results were displayed in the form of graphics. Through the simulation of specific engineering and test results of pile driving pressure, the results further showed that it was feasible to use the comprehensive correction coefficient to calculate the pile resistance. The obtained results could provide guidances for the design and construction of jacked pile under similar condition in engineering practice.
