摘　　要：以北京市顺义区某会展中心项目4号雨水调蓄池基坑工程为依托,通过对雨水调蓄池基坑支护方案比选及优化,选择最佳支护方式,并对拉森钢板桩支护桩头采取预应力锚索加固,使施工更加快捷、便利。结果表明:选择最佳基坑支护方式可加快施工节奏,并且尽可能减少对周边建筑物的影响。可见拉森钢板桩支护施工可以很好地适应各种复杂的施工现场实际情况,并根据实际情况对基坑支护进行优化设计,使设计与施工现场充分结合,更好地引导现场施工。The project was based on the foundation pit project of No.4 rainwater storage tank of an exhibition project in Shunyi District of Beijing.By comparing and optimizing the support scheme of the rainwater storage pit,the best support method was selected,and the Larsen steel sheet pile support is optimized in detail,so as to make the construction faster and more convenient.The results show that selecting the best effective foundation pit supporting method speeds up the construction rhythm and reduces the influence on the surrounding buildings as much as possible.It can be seen that Larsen steel sheet pile support construction can be well adapted to a variety of complex construction site actual situation,and according to the actual situation to optimize the design of foundation pit support,so as to fully combine the design and construction site,better guide the site construction.
