摘要
阐述了与复合地基桩土应力比大小有关的六个因素,着重分析了桩土面积置换率对桩土应力比的影响,介绍了一种比较简单的新的计算方法,通过计算公式说明了桩土面积置换率的基本含义,同时阐明了CFG桩的桩土面积置换率对基础设计时桩长、承载力等的影响。
It expatiates six elements concerned with composite foundation pole-soil stress ratio, typically analyzes the influence of pole-soil area replacing ratio to pole-soil stress ratio, analyzes a kind of easy new calculating method, by means of calculating formula it illustrates basic implication of pole-soil area replacing ratio, simultaneously elucidates influence of pole-soil area replacing ratio of CFG pole to pole length and loading power in process of basic design.
