摘　　要：本研究针对某矿山排土场边坡稳定性进行了深入分析,并提出了相应的治理策略。通过地质勘探和调查,收集了边坡的工程地质和水文地质数据。利用岩土力学和土工试验方法,发现边坡主要存在土层强度不足导致的抗滑移稳定性问题。为此,提出了分级设置抗滑桩和坡面防护的加固措施,以及在坡顶和坡面设置截排水沟,形成完整的排水系统,以增强边坡稳定性。定量分析和效果评估表明,这些措施能显著提升边坡稳定性。研究结果对矿山排土场的安全运营具有重要意义,并为类似工程提供了参考。This study conducted an in-depth analysis of the stability of the slope in a certain mine's dumping site and proposed corresponding treatment strategies.Through geological exploration and investigation,engineering geological and hydrogeological data of the slope were collected.Using geotechnical mechanics and geotechnical testing methods,it was found that the slope mainly suffers from anti slip stability issues caused by insufficient soil strength.To this end,reinforcement measures such as graded anti-skid piles and slope protection were proposed,as well as setting up interception and drainage ditches at the top and surface of the slope to form a complete drainage system to enhance slope stability.Quantitative analysis and effectiveness evaluation indicate that these measures can significantly improve slope stability.The research results are of great significance for the safe operation of mining waste disposal sites and provide reference for similar projects.
