摘要
简要介绍了近年国内人工冻结法在地铁隧道联络通道和隧道进出洞施工中的应用。根据人工冻土的物理力学性质和工程中的问题,将已有成果主要分为施工现场监测、室内与模型试验、理论与数值模拟三部分进行讨论,总结了有关施工工艺的改进、温度场在施工过程中的发展、冻胀融沉引起位移的预测、理论建模和多场耦合的数值模拟等研究进展,并提出一点建议。
The achievements in artificial freezing method applied to connecting passage of metro tunnel and the driving-in and driving-out techniques of shield driven tunnel are summarized in detail, which include the recent development in China. According to the physical and mechanical properties of artificial freezing soils and engineering problem, three aspects of research are involved as follows:measured data of construction, laboratory tests and model tests, the oretical analysis and numerical simulation.
