摘要:
提出了桩间“加筋与遮帘”作用的计算方法.单桩的桩土作用关系采用荷载传递曲线,根据弹性理论Mindlin方程求解群桩间相互作用.依据弹性叠加原理,建立了杆系结构有限单元法与荷载传递迭代法相耦合的群桩沉降计算混合法.在编制的群桩沉降分析计算程序GPSA1中,采用本文提出的计算方法成功地计算了群桩间的“加筋与遮帘”作用.同时,在计算桩间影响系数时,考虑了桩周介质压缩层厚度有限的边界条件.本文的计算方法,可作为群桩沉降分析研究的参考.
Abstract:
The method of calculating the “reinforcement and curtain” is produced. The soil behaviour of individual pile is modelled using load transfer curves and the pile-soil-pile interaction is determined based on Mindlin’s solution. Based on the superposition of the displacement fields of individual pile within the group, a hybrid method of Finite Element Analysis of rod structure coupling with Load Transfer Approach for calculating piles groups settlement is established. In the program GPSA1 written for predicting settlement of piles groups, the expression given in this paper is employed to consider the “restraint” action between piles, and, furthermore, the vertical displacement-influence factors are adjusted approximately by the boundary condition of the finite compressible layer depth. The documentation provides a guidance for future research in the analysis of piles groups settlement.
