本文从研究淤泥质粘土冻结后的力学性能以及冻土墙稳定性模型试验入手,探讨冻结法在软土深基坑施工中应用的可行性.研究结果表明:在一定条件下,利用冻土墙进行深基坑维护是可行的.
This paper starts with studying the mechanical properties of silt clay after freezing and the model test of the stability of frozen soil wall, and discusses the feasibility of the application of the freezing method in the construction of soft soil deep foundation pits. The results show that under certain conditions, the frozen soil wall is used. It is feasible to carry out deep pit maintenance.
