深基坑支护中冻土墙力学特性研究综述

Comment on research of mechanical characteristics of frozen soil walls in deep foundation pit support

人工土冻结技术在地下工程中的应用日益受到国内外重视 对冻结法设计中冻土墙厚度的各种确定方法进行了阐述与分析 另外,还阐述了冻土墙稳定性 可靠性设计的思路和具体内容。

Artificial ground freezing techningue will be used extensively in the underground construction, with ever increasing attention paid at home and abroad. Each method of frozen wall thickness was analyzed. The vavious methods for determining thickness of a frozen soil wall are described and analyzed. Meanwhile, the tranin of thought and concrete contents of designing frozen soil walls' stability and reliabllity are also expounded. Finally, its research direction in future is proposed.
