摘要
在三峡库区滑坡地质力学模型试验研究基础上,阐述了滑坡地质力学模型试验的研究现状,指出时间相似比在滑坡模型相似判据研究中须慎重选择;提出以重晶石粉系相似材料能较好模拟软土体滑坡;并介绍了模型相似材料测试中低参数指标测试存在的问题以及模型试验测试技术中的最新进展.
Based on the study on the geomechanics modeling test for landslide in the region of Three Gorges Reservoir, the status of the study on the geomechanics modeling for the landslide is presented, in which it is indicated that the time similarity ratio must be carefully selected during the study on the similarity criteria for the landslide model, and then it is put forward that the landslide of soft soil can be better modeled with the material of baryte powder.Furthermore,the problems of the lower parameter index in the similar model material testing and the recent advance of the technology for the modeling concerned are introduced as well.
