摘要
瑶来滑坡为一蠕滑-拉裂牵引式土质滑坡。通过分析地质环境条件和基本特征,查明了滑坡形成机制,并运用极限平衡法对其稳定性进行了定量评价。计算结果表明,在天然或地震状态下滑坡处于基本稳定状态,在持续降雨(暴雨)状态下滑坡处于欠稳定状态,存在有整体滑移的可能性。结合工程实际情况,提出"地表截排水+抗滑桩+桩板墙"治理措施,为河南省相关类型滑坡防治提供参考案例。
Yaolai landslide is a creep tensile traction type landslide.By analyzing the geological environmental conditions and basic characteristics,the formation mechanism of the landslide is identified,and the stability of the landslide is quantitatively evaluated by the limit equilibrium method.The calculation results show that under the condition of natural or earthquake,the landslide is in a stable state,and in the condition of continuous rainfall（rainstorm）,the landslide is in the unstable state,and there is the possibility of the existence of the whole slip.Combined with the actual situation of the project,this paper put forward measures of surface integrated drainage,anti-slide pile and sheet pile wall,to provide reference for the prevention and treatment of related types of landslide in Henan Province.
