摘要
主要阐述复杂地质条件下,深基坑冲孔咬合排桩的技术应用,以咬合桩等代地下连续墙,用等效刚度法计算排桩的等效连续墙厚度刚度,并对插入比进行分析取值。工程实例采用有限元软件建模分析,对深基坑在土压力、静水压力下排桩支护进行安全性验证分析,并详细阐述了冲孔咬合排桩施工技术全过程。
The technical application of deep-pit puncturing and squeezing piles under complex geological conditions were mainly described.The equivalent continuous stiffness method was used to calculate the equivalent continuous wall thickness stiffness of the piles and the insertion.More than the value of the analysis.The engineering example was modeled and analyzed by finite element software.The safety verification analysis of the deep foundation pit under the earth pressure and hydrostatic pressure was carried out,and the whole process of the construction technology of the punching and lining pile was elaborated.
