摘要
在试验资料的基础上采用了三维有限元数值仿真技术 ,再现了新型支盘桩的受力机理、荷载传递性状和荷载作用下应力场及位移场的变化规律。在此基础上 ,根据应力场及位移场变化的范围 ,指出了支盘桩的最佳盘间距、桩间距 。
The 3D-finite element numerical simulation was adopted, and bearing mechanism, loading transfer behavior and varying law of stress and displacement field of squeezed branch pile are reproduced successfully based on results of static loading test. Optimal spacing of disks and piles are pointed out according to the varying bound of stress and displacement field, and an important basis of quantization are provided for optimazing design and construction of squeezed branch pile.
