摘要
首先对南大沟排土场水文工程地质进行了调查分析,研究了排土场散体和地基土物理力学性质,在此基础上运用极限平衡法就南大沟排土场现状进行了稳定性分析,并结合南大沟排土场现状以及堆存方式,对影响南大沟排土场稳定性的因素进行了简要分析。通过分析得到排土场目前处于稳定状态,雨季时当排土场内地下水来不及时排出时,排土场的稳定性将大幅度降低,存在较大安全隐患,建议矿山应做好排土场安全监测、排水及支护工作。
Based on the study of the engineering geological characteristics of Nan da gou dumping site and the analysis of the failure mode of dump landslide,the present stability of the dumping site are analyzed.The dump stability is then analyzed and the measures for the comprehensive treatment of the dump are proposed.It is concluded that： when in rainy season,the stability of the dumping site will be greatly reduced if the underground water in the dump cannot be drained timely,representing a great hidden safety danger;the safety monitoring,drainage and baffling of the dump should be well done.
