摘要
通过大量的相似材料配比试验研究证明，在材料中加入一定浓度适量的Ｎａｃｌ溶液是实现覆岩破坏稳恒电场特征相似材料模拟的最佳方法。试验得出了相似材料电阻率与Ｎａｃｌ溶液浓度的关系。按照这一关系配制的相似材料模型的试验结果准确地反映了覆岩破坏稳恒电场的变化特征。
Numerous tests for the proportion of Similar materials mixture demonstrated that adding the right amount of Nacl solution is the optimum method by which we can achieve the simulation of constant electric filed feature in failure of overlying strata. The relationship between the similar material resistivity and the concentration of the Nacl solution was obtained by tests.The test results of the similar material model which was built according to the relationship have accurately reflected the canstant electric field features in the failure of overlying strata.
