摘要
排土场堆积物料力学参数的合理确定是准确评价排土场稳定性和进行排土场灾害防治控制一项关键工作。由于排土物料的复杂性,使排土场散体强度参数的合理取值成为困扰岩土工程界的难题。本文以某矿山排土场所存在的一个现状临界滑坡为依托,采用参数反演方法验算某矿山排土场物料综合抗剪强度,从而为分析该矿山排土场边坡稳定性提供准确的参数。
It is key to get the accurate mechanics parameters for accumulation of waste dump of mine , which is used to accurately evaluate the stability of waste dump of mine and to prevent disaster in waste dump of mine .The complexity of waste dump and material makes it a difficulty in rock engineering field to get accurate value for granular strength parameter of waste dump .In this paper ,based on current critical landslide of one waste dump of mine in the rainy surroundings ,it applies the method of parameter inversion to compute the comprehensive shear strength of material in this waste dump of mine ,which will provide accurate parameters to analyze the slope stability for waste dump of mine in rainy conditions .
