给出冻土蠕变实验的相似条件。认为在一定条件下冻土蠕变符合Boltzmann叠加原理,可以用光粘弹性方法进行模拟实验。作为实例,进行了刚性压块及桩式基础作用下的冻土蠕变平面问题光粘弹性模拟实验,首次得到了这方面的冻土预报的成果。
The similar conditions of creep experiment in permafrost are given. It is considered that the creep of permafrost under certain conditions conforms to the Boltzmann superposition principle and can be simulated by the method of light viscoelasticity. As an example, the light viscoelastic simulation experiment of the creep plane of frozen soil under the action of rigid briquetting and pile foundation is carried out. The results of permafrost prediction in this aspect are obtained for the first time.
