云南新平县耀南村滑坡成因机制分析及防治

THE GENESIS MECHANISM ANALYSIS AND PREVENTION OF YAONANCUN VILLAGE SLOPE SLIP IN XINPING,YUNNAN

云南新平县耀南村滑坡体属于高山峡谷高位滑坡,势能大,具备高速远程滑坡—碎屑流特征,高强度降雨是滑坡产生的直接诱发因素。自2002年至今,该滑坡体长期处于蠕滑变形状态,已造成南恩希望小学教室开裂和南恩社房屋变形,对当地的教学和生活、生产造成了重大影响。滑坡体还威胁着下游戛洒镇的安全。治理措施主要采用截水沟和抗滑桩相结合的方法进行坡体稳定性加固治理。

Yaonancun village slope slip body in Xinping,Yunnan is a high position slope slip,with a very high potential energy,characterized by high speed far distance slip-clastic flow.The direct induced factor of slope slip is the high intensity raining.Since 2002,This slope slip has been in the creepage slip deformation state for a long time,which has been causing Nanen hope primary school classroom to be split and Nanen community house deformation,serious influence on the local education,life and production.Moreover,the slope slip body is also the threat against the safety of lower reaches Gasa town.The main prevention measure is to consolidate the stability of slope by the method in combination of water interruption channel and anti-slip pile.
