某厂房桩基挤土效应分析及处理

Soil Squeezing Effect Analysis and Processing of Some Plant

预应力高强混凝土管桩属预制桩,施打过程中会产生挤土效应,可能引起桩偏位或桩质量问题,施工中应高度重视并采取相应的有效措施。文中介绍某厂房管桩施工后因挤土效应引发部分管桩偏位问题,根据桩基检测情况分析其原因,并提出了相应的加固处理方案。

Soil squeezing effect may be caused by pile displacement or pile quality problems.The construction unit should take seriously highly,take corresponding measures against soil effective.In this paper,it is combined with a building adopting prestressed high-strength concrete pipe pile sinking pressure piling construction,part of pipe pile by squeezing soil effect caused part of tubular pile displacement problems,according to the inspection of pile foundation,the reasons of pile are analyzed,put forward corresponding reinforcement scheme.
