摘要
拉森钢板桩施工速度快,插入地层即具有强度,成桩到基坑开挖施工工期很短,但简易支护情况下,不加围檩或内撑,桩身产生的侧位移较大.论文通过一具体工程案例,详细分析该工程拉森钢板桩侧位移较大的原因,为避免类似问题的发生提供参考.
Abstract
The construction speed of larsen steel sheet pile is fast,and it has strength when inserted into the ground.The construction period from pile formation to excavation of the foundation pit is very short.However,in the case of simple support,without adding purlins or internal supports,the lateral displacement of the pile body is relatively large.This article provides a detailed analysis of the reasons for the large lateral displacement of Larsen steel sheet piles in a specific engineering case,in order to provide reference for avoiding similar problems.
