基于水动力的典型矿山泥石流运动模式研究
Study on typical movement model in mine debris flow based on hydrodynamic force conditions
摘要
Abstract
Some artificial accumulations of slag become more broken caused by“4·20”Lushan earthquake in 2013. Hougou is a typical mines debris flow susceptible region in earthquake zone of Shimian County. The motion pattern of its debris flow is closely related with terrain, hydrologic, static and dynamic, and material conditions. Since there are differences in motion patterns of man-made and natural debris flows, this study started with the four conditions and took Hougou debris flow as an example to discuss the mo⁃tion pattern of mine debris flow in detail. The results show that the process of Hougou debris flow involves the following five aspects:(a) stability of waste slag reduced by initial rainfall;(b) slag slope eroded by continuous rainfall;(c) channel slag moving stimulated by rainwater;(d) debris flow forming with high content of slag torrent,and (e) debris flow scale enhanced by slag erosion along the gully.关键词
