Abstract:It is an important precondition and basis for the design of tailings reservoir and its safety facilities by reasonably judging and estimating the mud-sand flow hazard due to dam-break. In this paper, the mud-sand flow hazard scope, extent and spatial state after dam-broken of heightened Mawuqing tailing dam were simulated and analyzed through a flood and debris flow numerical simulation approach, and the hazard risk grade of different spatial locations of downstream Xiaoqingkou(XQK) village was obtained from t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
