摘要
边坡地质灾害工程防护措施主要包括削坡、挡土墙、格构锚固、砌体、喷锚、防护网、排水等,一般采用2种或多种形式组合以达到治理地质灾害的目的,这些方式均基于减少下滑力、增大抗滑力、阻止岩土下滑的思想理念。以广东中山地区为例,在分析中小型地质灾害特征的基础上,基于“绿色”理念,提出注重边坡管理,由“防滑”治理向“放滑”排险方式转变,采用清表、拦石(土)墙(网)、植被护坡和被动防护网等快速简易排险方法,为山体“松绑减压”,也为地质灾害防治工作“松绑减压”。
Geological disaster protection engineering measures for slope mainly include cutting slope,retaining wall,lattice anchor-age,masonry,spray anchor bracing,fence,drainage,etc.,usually in the form of two or more combinations to achieve the purpose of management of geological disasters.These methods are based on the idea of reducing sliding force,increasing sliding resistance,and preventing geotechnical slide.Taking Zhongshan area of Guangdong Province as an example,on the basis of analyzing the characteristics of the small and medium-sized geological disasters,following the green development concept,this paper proposes to pay attention to slope management,change from″slide prevention″to″slide release″,and adopt rapid and simple risk removal methods such as surface cleaning,rock-blocking(soil)wall(net),vegetation slope protection and passive prevention net,so as to″loosen the binding force and reduce pressure″for the mountain,and also for the geological disaster prevention and control.
