黏土隔水层的应力应变全程相似模拟材料和配比实验研究
Experimental study of simulation material and matching for whole stress and strain process of clay aquiclude
摘要
Abstract
By testing the clay and loess of aquiclude of Yushuwan coal mine,the original stress-strain is obtained. Based on the past researches, the simulation materials are determined to use sands, clay, oil, and water. According to the single-factor analysis method, material matching tests are carried out. The proper simulation materials and its proportion are obtained by comparing factors of peak-strength and strain as well as the residual strength and strain in the whole stress-strain curves of aquiclude simulation materials. It is found that the general lubricating oil is the good influence agent for material plasticity and the proper material matching of clay aquiclude simulation material is obtained. This research rea-lizes the whole stress-strain using materials for simulating clay aquiclude. It provides an effective way for studying the aquifer stability and water conservation in mining.关键词
