摘要 介绍了Hoek-Brown法岩体力学参数的确定方法及其原理,并以某铜矿岩体力学参数确定为例,用FLAC3D三维有限差分法建立了该矿的深部开采模型,对所确定的岩体力学参数进行了工程检验。计算结果表明,三期矿体开采结束后,地表下沉计算值与实测值基本吻合,说明所确定的岩体力学参数可以作为四期矿体深部持续开采地表变形和岩体移动的计算基础数据,同时,也表明用Hoek-Brown法确定岩体力学参数对于实际工程具有重要的参考价值。 This paper introduces the determining method and its principal of rock mass mechanics parameters selection in terms of Hock-Brown Method, and taking the determination of rock mass mechanical parameters of a copper mine as an example, establishes a deep mining model of this mine by three-dimensional finite difference method FLAC30 which can carry on project quality inspection of the determined mechanics parameters. The numeric result indicates that the calculated value of ground subsidence is fit to measured value basically after the third phase ore body mining, which shows the determined mechanics parameters can be used as the calculating foundation data for the surface deformation and ore body movement during fourth phase ore body deep sustaining mining, at the same time, it also shows that the Hock-Brown Method determining mechanics parameters has important reference to practical project.
