Study on Bearing Properties of Rammed Soil-Cement Piles Composite Foundation
-
摘要: 采用桩与土共同作用的线性分析方法,分析和解决夯实水泥土桩复合地基承载力设计问题。研究发现:面积置换率、褥垫层厚度和桩刚度对桩土分担比率的影响,群桩基础条件下桩的沉降等规律。提出的方法可用于复合地基承载力优化设计。Abstract: The linear analysis method with soil-pile interaction is used to analyse the bearing capacity of rammed soil-cement piles composite foundation. The following results are abtained:the influence of replacement ratio of area, subcrust thickness and pile stiffness on partaking ratio of pile and soil, and the displacement of the single pile in pile group. The method mentioned above can be used for optimization design of bearing capacity of composite foundation.
