摘要

降雨是岩体强度降低重要影响因素,对于厚软基底而言,如何分析和预测降雨量大小对排土场安全的影响程度是矿山技术人员探索的主要问题。本文以某露天排土场为例,就降雨量大小对排土场的影响特性进行了数值模拟分析与预测研究,从中得到了随着降雨量增加,塑性破坏区不断增大,并逐渐形成滑移破坏面的过程,由此为排土场的安全治理与工程设计提供了决策依据。
rock mass strength is decreased due to rainfall.main problem is probed by mine technician to analyzed influence degree for waste dump safety due to rainfall quantity.This paper take a surface waste dump as an example,numerical simulation analysis prediction study on waste dump influence feature are carries out for rainfall quantity,plastic zone is enlarged and sliding face is informed as rainfall is increased.and then deciding basis is provided for safe control and engineering design of waste dump.
