摘要
本文介绍底摩擦模型法的发展和应用,底摩擦模型同重力场中的岩土体的相似原理,以及模型及相似材料的参数选择。认为底摩擦模型法使用方便、经济、结果可靠,是研究岩土工程问题的一个重要工具。
The method of base friction models is used to simulate the effcts of g-ravity in two dimensional physical models of engineering in rock and soil. The mouel lying on one base of plane moves relatively to the plane, between them i frictional force developed which is applied to imitate gravity. Because the model, apparatus and applicatron of the method are simple, especially the whole processs of the model's destruction can be observed directly and successively in the test, the method is a important means to study problems in rock and soil engineering.
The development and use of the method, the analogy and its design between the model and gravity are illustrated in this paper
