摘要
以南京地铁许南区间联络横通道为例,利用温度场理论,采用非线性有限元程序TEMP/M,对水平冻结过程进行了仿真分析,揭示了冻结锋面随时间变化以及冻结帷幕的交圈和扩展过程。最后指出了人工土冻结技术中今后应重点探讨的相关问题。
This paper studied a connecting aisle of one metro,using temperature field theory,implement the simulation analysis of its horizontal freezing process,revealed the formation and expansion laws of frozen curtain,and obtained valuable results,which can be a good reference to engineering practice.
