排土场滑坡与泥石流灾害控制技术与方法

Controlling Technique for Disasters of Dump Landslide and Debris Flow

对排土场滑坡破坏模式进行了FLAC3D模拟分析。结合具体工程实例,分析形成潜在滑坡、泥石流灾害的原因。针对排土场灾害,强调以防为主,防治结合的思想。提出以逆序排土工艺及倾斜分层排土工艺进行排土,提高排土场自身稳定;结合坡面疏导排水、底部泄流体等综合技术,对排土场灾害进行防治。对排土场灾害的预防与治理有一定的借鉴意义。

FLAC3D simulate analysis of the breach pattern of the dump. Analyze the latent factor of the appearance of the dump and debris flow; combine with the specific project examples. Aimed at the disaster of the dump, stressing both prevention and management while with emphasis on prevention. Bring forward the techniques of the reversed waste disposal and the sloped delaminating waste disposal to improve the stabilization of the waste dump; Prevention and control the dump disaster with the combination of hill slope leading drainage and the bottom effusion system, which would provide some reference meaning to both the prevention and management of the waste dump disaster.
