Numerical Simulation Research on Rigid-flexible Piles

The rigid long piles and flexible short piles which under the free state has carried out system test, firstly it has carried on the pile body completeness inspection before test, then to carry out the free state of rigid pile and flexible pile and composite foundation static load test of pile type respectively. The bearing capacity of composite foundation with three cases of mechanism has carried on the comparative analysis, through the experimental study on the scene in regard to more type pile composite foundation and the free state of the stress and displacement of single pile foundation, analysis of pile composite foundation can better understand the understanding of the mechanism of action and give a correct evaluation of actual project.
