深层搅拌桩施工挤土效应分析
摘要:深层搅拌桩作为软土地基处理的一种新方法,正越来越多地被应用到基础工程中去。实践证明,深层搅拌桩也存在挤土效应。结合工程实例,对相关的墙体侧向位移和管道沉降的监测数据进行了分析,总结出了搅拌桩挤土效应的特点及其在不同的施工工艺所表现出来的规律,并分析了可能导致这些规律的原因。用Sagaseta的源-汇理论得到的位移计算公式对这些规律进行了研究。
Abstract:The deep mixing pile, which is a new groundwork construction method, generally used in soft soil, is being widely popularized in foundation construction fields. It has been proved that mixing pile construction would also cause soil-squeezing effects.On the basis of research and analysis by former scholars, the monitor data of wall lateral displacement and pipe sedimentation related to an engineering project are analyzed and the characteristics of the soil-squeezing effects as well as the rules of it are summarized under different construction crafts. Finally, these rules are researched by the formulas of displacement based on Sagaseta's source-sink image technique.
