摘要
以贺州市平桂区思红滑坡为例,进行滑坡特征和稳定性分析,提出了滑坡防治建议.研究结果表明:思红滑坡由于黏土层透水性强,且风化层遇水极易软化,雨水入渗形成软弱夹层,诱发局部变形最后发生滑动;在天然工况下,滑坡处于基本稳定状态,在暴雨工况下,滑坡处于欠稳定状态.建议对该滑坡采取"支挡+地表排水"的防治措施,并安装地质灾害专业监测设备进行监测.
Abstract
Taking Sihong Landslide in Pinggui District,Hezhou City as an example,the characteristics and stability of landslide are analyzed,and the suggestions of landslide prevention and control are put forward.The results show that the Sihong Landslide,due to the highly permeability of the clay layer,and the weathered layer is easily softened when exposed to water,the rainwater infiltration forms a weak interlayer,which induces the local deformation and finally slides.Under the natural condition,the landslide is basically stable,while under the rainstorm condition,the landslide is understable.It is suggested to adopt the prevention and control measures of"supporting and retaining+surface drainage"for this landslide,and to install professional monitoring equipment for geological disaster.
