摘要
随着地下工程的不断发展,岩爆成为严重影响施工安全的地质灾害,为了研究岩爆发生机理及防治措施,以宜昌后坪磷矿岩爆灾害为工程背景,现场采取后坪磷矿岩爆区域岩样,运用GCTS系统岩石三轴仪进行室内岩石三轴试验,分析围岩物理力学参数,通过岩爆预测深度判据,预测岩爆发生的深度,并利用三轴试验下的声发射三维定位技术,分析岩爆发生机理,并为工程岩爆预防及处理提供对应措施。
With the continuous development of underground engineering,rock burst has become a serious impact on the construction safety of geological disasters,in order to study the mechanism and control measures of rock burst,based on the engineering background of the rock burst disaster in Yichang,taking the rock samples of the area of the post,using the GCTS system three axis rock to carry out the indoor rock test of three axes,the physical and mechanical parameters of surrounding rock are analyzed,the depth of rock burst was predicted by the rockburst prediction criterion,by using acoustic emission three-dimensional positioning technique under triaxial test,the mechanism of rock burst is analyzed,based on these,corresponding measures are provided for prevention and treatment of rock burst.
