摘要
基于布辛奈斯克(Boussinesq)和明德林(Mindlin)解,结合软土中水泥土搅拌桩复合地基的沉降变形特点,探讨矩形荷载下水泥土搅拌桩复合地基的沉降计算,研究下穿通道与滑行道间差异沉降控制的变形协调分析方法和设计原则。
Based on the illustration of Boussinesq and Mindlin, and combined with the settlement and deformation characteristics of cement-soil mixing pile composite subgrade in the soft soil, the article discusses the settlement calculation of cement-soil mixing pile composite subgrade in rectangle load, and studies the analysis method and design principle of deformation compatibility to control the difference and settlement between the underpass and taxiway.
