摘要
地层冻结加固法是盾构隧道进出洞工程中的重要工法。对盾构进出洞地层冻结加固法涉及到的冻结加固体设计计算方法、垂直冻结温度场和水平冻结温度场理论及其在冻土帷幕厚度和平均温度计算方面的应用研究现状进行了回顾与总结,分析了目前研究的不足之处,并对盾构进出洞地层冻结法研究提出了建议。
A ground freezing reinforcement method is an important construction method in the shield tunneling break-in and out engineering.A review and summarization was conducted on the ground freezing reinforcement method of the shield break-in and out related to the applied study status on the design calculation method of the freezing reinforcement mass,the vertical freezing temperature field and the horizontal freezing temperature field theory as well as the freezing soil curtain thickness and average temperature calculation.The paper analyzed the shortages of the present study and provided the proposals on the study on the ground freezing method of the shield break-in and out.
