【摘要】：冻土工程实践的发展和需求不断给冻土工程提出新的问题。冻土离心模拟技术是专门针对冻土工程的物理模拟技术,即在已有的土工离心机的基础上实现了温度场与应力场的耦合,并可在较短的时间内完成对大跨度时间下冻土工程实际问题的模拟。近30年来,随着热交换装置不断革新、相似准则不断完善以及试验方法不断创新,使得冻土离心模拟技术在世界范围内发展迅速,为冻土工程问题的研究开辟了新的途径。本文介绍了试验装置的发展过程,综述了已开展的主要试验及研究成果,在此基础上展望了冻土离心模拟技术未来的发展方向。冻土离心模拟技术在冻土工程领域中将拥有广阔的应用前景。
[Abstract]:The development and demand of permafrost engineering practice continue to put forward new problems for permafrost engineering. Frozen soil centrifugal simulation technology is a special physical simulation technology for frozen soil engineering, that is, the coupling of temperature field and stress field is realized on the basis of the existing geotechnical centrifuge, and the simulation of practical problems of frozen soil engineering in long span time can be completed in a relatively short time. In the past 30 years, with the continuous innovation of heat exchange equipment, the continuous improvement of similarity criteria and the continuous innovation of test methods, the centrifugal simulation technology of frozen soil has developed rapidly in the world, which has opened up a new way for the research of permafrost engineering problems. In this paper, the development process of the test device is introduced, the main tests and research results are summarized, and the future development direction of centrifugal simulation technology for frozen soil is prospected. The centrifugal simulation technology of frozen soil will have a broad application prospect in the field of frozen soil engineering.
