摘要
在以粉砂土为主的中软土地区,静压PHC管桩施工过程中易产生较明显的挤土效应,会对周边建筑物造成一定影响.文中以粉砂土地区静压PHC管桩施工为例,通过合理的沉桩顺序、控制日均沉桩数量等方式,减小挤土效应对周边建筑物的影响;通过对水平位移、深层水平位移、孔隙水压力的监测,验证桩基施工方案的可行性,确保施工顺利进行.该研究成果可为复杂环境下的静压PHC管桩施工提供参考.
Abstract
In areas with medium soft soil mainly composed of sandy soil,the construction process of static pressure PHC pipe piles is prone to significant squeezing effect,which has a certain impact on surrounding buildings.This article takes the construction of static pressure PHC pipe piles in sandy soil areas as an example,and reduces the impact of soil squeezing on surrounding buildings by adopting reasonable pile sinking sequence and controlling the daily average number of pile sinking.By monitoring horizontal displacement,deep horizontal displacement,and pore water pressure,the feasibility of the pile foundation construction plan is verified to ensure the smooth progress of pile foundation construc-tion.The research results of this article can provide reference for the construction of static pressure PHC pipe piles in complex environments.
