在软土地区进行基坑开挖时,对变形控制的要求往往比较高,钢支撑自动轴力伺服系统的应用,解决了上述问题。通过有限元分析,分别对多种假设情况的钢支撑自动伺服系统建立模型,得出围护结构侧移值和坑外地表沉降值,在与工程监测数据进行对比分析研究后证实:钢支撑自动伺服系统可以显著减少基坑围护结构侧移及地面位移量,可在工程中合理使用。

In the process of foundation pit excavation in soft soil area, the requirements of deformation control tend to be higher. However, the application of the steel support automatic servo system can solve the said problem. By finite element analysis, the different models of the steel support automatic servo system have been set up respectively under various assumptions. As a result, the lateral displacement value of the excavation support structure and the settlement value of the ground outside the foundation pit have been obtained accordingly. After comparison and analysis of the said values with the actual monitoring data, it has been proved that the steel support automatic servo system can significantly reduce the lateral displacement of the foundation pit support structure and the ground displacement, which can be properly used in the similar engineering construction.
