| 摘 要： | 2012年7月21日,北京地区发生了61年以来的最大降雨,特大强降雨引发房山区三合庄村泥石流地质灾害。为了最大限度的减少房山区三合庄村泥石流所带来的损失,本文选取该泥石流作为研究对象,采用了遥感解译和灾害地质实地调查等方法,确定了三合庄泥石流基本特征,从地形、物源和水源三方面研究了三合庄泥石流的成因,依据泥石流相关的防治工程勘查设计规范,采用雨洪法计算出三合庄村泥石流的活动特征,使用综合评分法判断了三合庄泥石流的易发性。

| Abstract: | Debris lfow is a kind of larger and more unexpected disaster than collapses and landslide-dominated in Beijing, which usually breaks out suddenly, ferociously and rapidly. It can cause significant casualties and serious property damage. On July 21, 2012, there occurred the largest rainfall in Beijing since 61 years ago, and brought debris lfow into the village of Sanhezhuang in Fangshan area of Beijing, with the threats all the time. The characteristics of the debris lfow were found from remote sensing interpretation and disaster geology survey. The cause of its formation was analyzed on landform, material sources and water source. The active characteristics were calculated with rain-lfood method and the formulas in Speciifcation of Geological Investigation for Debris Flow Stabilization. By using the comprehensive score method, it could judge and analyze the integrated scoring susceptibility of Sanhezhuang landslides. |
