摘要
作为一个多山的国家,中国山区面积在国土总面积中占比较高,可达到2/3,尤其是西南地区,山区面积已达到70%以上。由于山地众多,地质灾害频发,不仅影响了当地的经济发展,也对人民的生命财产安全造成了严重威胁。边坡崩塌是地质灾害的一种类型,崩塌过程中极易出现岩土失稳现象,顺着边坡失稳后的岩土迅速下滑,发生猛烈地碰撞,损毁边坡下方公路、建筑等构造物,具有极大危害性。基于此,在全面了解边坡崩塌类型、原因及形成机理的基础上,结合案例分析,从边坡稳定性角度出发,提出边坡加固方案,并由此提出了几点边坡崩塌地质灾害应急治理建议,希望能够为边坡崩塌灾害防治工作提供一定帮助。
As a mountainous country,Chinas mountainous area accounts for a relatively high proportion of the total land area,which can reach 2/3,especially in the southwest region,the mountainous area has reached more than 70%.Due to the large number of mountains and frequent geological disasters,it not only aff ects the local economic development,but also poses a serious threat to peoples life and property safety.Slope collapse is a type of geological disaster,which is prone to rock and soil instability in the process of collapse.After the slope instability,the rock and soil will slide and collide rapidly and violently,damaging the highway,buildings and other structures below the slope,with great harm.Therefore,on the basis of a comprehensive understanding of the types,causes and formation mechanisms of slope collapse,combined with a case,from the perspective of slope stability,this paper puts forward a slope reinforcement scheme,and then puts forward several emergency treatment suggestions of slope collapse geological disasters,hoping to provide some help for the prevention and control of slope collapse disasters.
