摘要
静压桩由于成桩速度快、龄期短、工期短、造价低等优点,已广泛应用于工程领域,但由于静压桩具有挤土作用,尤其是软土地区的静压桩,挤土效应非常明显,处理不好可能对周边建(构)筑物产生不同程度的破坏。从静压桩现场深层水平位移观测的角度对软土地区静压桩的挤土效应进行研究,分析了静压桩设置方案及不同地层对挤土效应的影响。
Static pressure has been widely used in engineering because of its fast forming speed, short age, short construction period and low cost. However, as the static pressure pile has the effect of squeezing soil, especially the static pressure pile in soft soil area, The effect of soil compaction is very obvious. If it is not handled properly, it may damage the surrounding structures to varying extents.The squeezing effect of static pressure pile in soft soil area is studied from the point of view of deep horizontal displacement of static pressure pile in situ. The settlement scheme of static pressure pile and the effect of different formation on the squeezing effect are analyzed.
