摘要

考虑了桩的加筋与遮帘效应，通过剪切位移法依据力与位移的协调条件得出桩的柔度系数。在此基础上建立土的成层性模型，根据桩顶与桩底的物理关系推导了桩顶沉降与荷载关系的解析解。通过工程算例进行比较，结果表明

以土层状模型建立的群桩沉降计算方法是可行的。分析表明

加固区土层不同分布对桩沉降有所影响，浅部土模量的提高有利于减小沉降。

Abstract

Considerating reinforcement and curtain effect

flexibility coefficient of pile is obtained by means of shear displacement method. Theoretical solution between settlement and load of pile is deduced according to physical relation of pile head and pile bottom on the basis of soil layered model. Comparative result of engineering example demonstrates that the pile groups settlement computation method is feasible. Moreover

the analysis indicates that the soil layered distribution in the reinforcement area influences the pile groups settlement; the increase of soil modulus can reduce its settlement effectively.
