人工冻结技术用于深基坑支护中的设计计算

The use of the design calculation of closed population technolodge in the support of deep-pit

针对一些含淤泥或者流砂等复杂地形的深基坑支护问题,介绍了人工冻结技术这一支护手段,并给出了冻土墙厚度和嵌固深度的设计计算方法以及如何进行冻土墙稳定性验算,为今后人工冻结技术在深基坑支护中的推广应用提供了依据。

This paper proposeb the closed population technolodge for the support of deep-pit in such as silt or quicksand complex stratam, gives the design calculation of the width of the frozen soil wall and the depth of the fixing, and how to check the stability of the frozen soil wall. It is a background for the use of the closed population in deep-pit project.
