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。
Taking the horizontal crossings of Xu Nan section of Nanjing Subway as an example, the horizontal freezing process is simulated and analyzed by using the temperature field theory and the nonlinear finite element program TEMP / M. The freezing front changes with time and the freezing circles’ Expansion process. Finally, it points out the related issues that should be focused on in the future of artificial soil freezing technology.
