滑坡稳定性分析及防治必要性评价OA
Analysis of Landslide Stability and Evaluation of the Necessity of Preventionand Control
文中以滑坡勘察成果为基础,先通过传递系数法开展滑坡稳定性评价,并利用P×C法进行滑坡防治必要性评价.分析结果表明,通过滑坡稳定性计算,2-2'剖面的稳定性相对最差,其次是3-3'和1-1'剖面,且暴雨工况的稳定性相对最差,属欠稳定-基本稳定状态,其余地震工况、天然工况多属基本稳定状态或稳定状态,即不利工况条件下存在较大的失稳可能.同时,经滑坡防治必要性评价,滑坡整体防治必要性得分为80.27,对应防治必要性等级为Ⅲ级,说明滑坡整体稳定性较差.最后,两类分析结果均表明滑坡防治具有明显的必要性,有必要尽快开展防治处理,确保区内居民生命财产安全.
To lay the theoretical foundation for landslide prevention and control,based on the results of landslide survey,the stability evalua-tion of landslides is first carried out using the transfer coefficient method,and the necessity evaluation of landslide prevention and control is car-ried out using the P×C method.The analysis results show that the stability of 2-2'profile is the worst,followed by3-3'and1-1'profiles,and the stability of rainstorm condition is the worst,which belongs to the under stable basically stable state.The other seismic conditions and natural conditions are basically stable or stable,that is,there is a greater possibility of instability under adverse conditions.Meanwhile,ac-cording to the necessity evaluation of landslide prevention and control,the overall necessity score of landslide prevention and control is 80.27,corresponding to the necessity level of prevention and control being III,indicating poor overall stability of the landslide.Finally,both types of analysis results indicate that landslide prevention and control is of significant necessity,and it is necessary to carry out prevention and control measures as soon as possible to ensure the safety of the lives and property of residents in the area.
