摘　　要：在城市密集建筑群中进行深基坑开挖越来越普遍,如何合理考虑已有建筑对支护结构的影响很大程度上依靠工程经验。本文根据CFG桩复合地基的传力机理,建立了深基坑开挖时土压力的分层简化计算模型;结合工程实例,探讨了该计算方法的合理性,对类似工程具有借鉴意义。Foundation pit excavation among dense city buildings is more and more popular. How to consider reasonably the influence of surrounding buildings mainly depends on engineers＇ experiences. In the article a simple numeration-model of soil pressure has been established based on multilayer loads prineipium. And the mechanism of CFG piles compound foundation is combined. Based on a engineering example, the rationality of the method is discussed. The article can be used as a reference for similar engineering.
