拉森钢板桩在软土地层深基坑支护中的应用

Design and discussion on Larsen steel sheet pile used in the deep foundation pit support of soft soil stratum

拉森钢板桩作为一种低碳环保、可回收的建筑材料,在各类建筑中发挥着重要的作用。以蕲春县某河道整治项目为例,选取了基坑支护工程中2个典型剖面,介绍了拉森钢板桩在软土地层中的应用,并将天汉软件设计计算结果、MIDAS GTS NX数值模型分析结果与基坑监测结果进行对比分析,三者得到的支护结构位移、受力数值较为一致,表明天汉深基坑设计软件的客观合理性及可靠性非常高,施工前可以用MIDAS GTS NX数字模拟来预测及引导施工。

Larsen steel sheet pile,as a low-carbon,environmentally friendly and recyclable building material,plays an important role in all kinds of buildings.Taking a river regulation project in Qichun County as an example,two typical sections of foundation pit supporting engineering are selected to introduce the application of Larsen steel sheet pile in soft soil stratum,and the design calculation of Tianhan software,the analysis results of MIDAS GTS NX numerical model and the monitoring results of foundation pit are compared and analyzed,and the displacement and stress values of the supporting structure obtained from the three are more consistent.It shows that the Tianhan deep foundation pit design software has high rationality and reliability,and the MIDAS GTS NX numerical simulation can be used to predict and guide the construction before construction.
