摘要
分析了刚性桩复合地基中垫层、桩及桩间土的共同作用机理,考虑复合地基中桩、土变形协调,提供一种计算复合地基桩土应力比的方法;在此基础上研究复合地基中垫层模量、桩端持力层模量、桩土相对刚度比、桩长径比、面积置换率等因素对复合地基桩土应力比的影响,分析刚性桩复合地基的承载特性。
Analyzing the cooperation mechanism of piles,soil and cushion,the method to calculate the stress ratio of piles to soil is introduced by considering harmony working of piles,soil and cushion in composite foundation.The factors influencing the stress ratio of piles to soil,such as cushion modulus,soil modulus of piles end,rigid ratio of pile and soil,pile length,area displacement ratio,are discussed by calculating stress ratio,and the bearing behavior of rigid pile composite foundation are analyzed.
