| 摘 要： | 云南师宗县高良码头公路西侧古滑坡为一中型推移式土质滑坡,滑坡体规模30.8万m3。该古滑坡曾造成南盘江短期堵塞,之后古滑坡堆积体处在临界稳定状态。由于修建的省道S207公路从滑坡下部通过,古滑坡堆积体开始蠕动,2013年8月滑坡堆积体加剧蠕动变形,后缘弧状拉张裂缝及错台变形强烈。通过多次实地调查,激发古滑坡堆积体蠕动因素有降水、地震、动荷载等,目前古滑坡堆积体处于不稳定状态,建议一是采用抗滑桩及滑体外围设置排水沟等工程治理,二是搬迁避让,确保生命和财产安全。

| Abstract: | The old slide on W side of Gaoliang Dock highway of Shizong,Yunnan is a middle scale move earth slide,with slide body 30.8 thousand cubicmeters.It has resulted in the blocking of Nanpanjiangriver in a short time.Afterwards,the old slide accumulation body is in a critical stable state.Because the built province road S207 highway passes the lower part of slide,the old slide accumulation body begins to wriggle.In August 2013,the slide body wriggle and deformation strengthened,the back edge arc tension crack and displacement platform deform intensely.According to the survey on the spot many times,we think the derivation factors of old sllde accumulation body wriggle are precipitation,seism and movement load,etc.At present,the old slide accumulation body is unstable.We suggest,1.Engineering control,ie set up anti-slide pole and build water drainage ditch around the slide body,2.Migration and avoidance in order to protect the safety of life and property. |
