以数值模拟的方法分析研究了变刚度布桩复合地基的沉降影响因素。分别考察了筏板厚度、褥垫层厚度和模量、桩间土模量、桩端土模量变化对变刚度布桩复合地基沉降性状的影响。
The influencing factors of settlement of composite foundation with variable stiffness pile are analyzed by numerical simulation method. The influences of the thickness of raft, the thickness and modulus of cushion, the modulus of soil between piles and the modulus of soil at pile tip on the settlement of composite foundation with variable stiffness were investigated respectively.
