摘要
文中以子长至姚店公路徐家岔村滑坡为研究对象,根据其地貌特征、地质条件、水文特征和坡体结构等,并结合现场勘察结果,阐述了滑坡发生特征及成因机制。文中采用瑞典条分法,对该滑坡主滑剖面按不同工况进行了稳定性分析评价。研究结果表明,该滑坡在天然及天然+地震的状况下处于稳定状态,满足设定的安全系数1.25的要求,在饱和及饱和+地震的状况下处于基本稳定状态,不满足设定的安全系数1.25的要求。
The article takes the Xujiacha Village landslide on the Zichang Yaodian Highway as the research object.Based on its geomorphic characteristics,geological conditions,hydrological characteristics,and slope structure,and combined with on-site survey results,the characteristics and mechanism of landslide occurrence are elaborated.The Swedish slice method was used to analyze and evaluate the stability of the main sliding profile of the landslide under different working conditions.The research results show that the landslide is stable under natural and natural+earthquake conditions and meets the requirements of the set Factor of safety 1.25.It is basically stable under saturated and saturated+earthquake conditions and does not meet the requirements of the set Factor of safety 1.25.
