摘要
进行软岩支护研究有必要进行大量的模型蠕变试验,这对模型材料提出了更高的要求。砂一石蜡混合材料能很好地模拟煤矿软岩(如泥页岩).文中给出了材料的配比试验和蠕变试验的结果,得到按对数型蠕变方程和西原模型蠕变方程拟合的回归系数。
It is neccessary to make a lot of material creep tests to study the soft rock support, that puts in higher claim for the equivalent material. Sand-wax mixed material can well simulate soft rock in mine such as clay-shale stone .In this paper, the results of the mixing ratio test and creep test of the mixture are given, with the regression coefficients according to logarithmic creep equation and K-B model's creep equation.
