摘要

利用物理试验和有限元计算方法,针对单柱复合筒型基础在工程应用中的施工效应进行分析,总结单柱复合筒型基础顶承式承载模式,并基于其承载特点提出在浅覆盖岩层提升承载能力的有效方法。研究表明：施工效应的影响在循环荷载作用过程中逐渐减弱;单柱复合筒型基础为顶承式承载模式,采用等效重力模型对基础的极限承载力模拟可较好地反映单柱复合筒型基础的承载特性,且可通过等效重力模型手段对单柱复合筒型基础进行简化计算;压载能够有效提升单柱复合筒型基础在浅覆盖岩层地质中的适用性。

Abstract

Based on the physical test and finite element calculation method, the construction effect of mono-column composite bucket foundation in engineering application is analyzed, and the top-bearing mode of mono-column composite bucket foundation is summarized. The effective method to improve the bearing capacity of shallow bedrocks is proposed based on its bearing characteristics. The results show that： the influence of construction effects gradually weakens during the cyclic loading process. The bearing capacity of mono-column composite bucket foundation is mainly exerted by the top cover, the simulation of ultimate bearing capacity using equivalent gravity model can better reflect the bearing characteristics of mono-column composite bucket foundation, and the calculation of mono-column composite bucket foundation can be simplified through equivalent gravity model. It can be seen that ballast can effectively improve the applicability of mono-column composite bucket foundation in shallow bedrocks.
