摘要
云南楚大高速公路九顿坡隧道洞口滑坡 ,是由于施工中破坏已稳定的古滑坡坡角 ,而造成山体失稳所形成的滑坡。由于发现及时 ,采取了监测措施 ,进行了有效的预板分析计算 ,达到滑坡防治与处理的效果 ,可供类似施工工程借鉴。
The landslide at Jiudunpo tunnel portal of Chuxiong-Dali expressway in Yunnan Provice was a kind of landslide which was formed because of the stability failure of rock mass during construction destroying the slope section of a stablized ancient landslide. The landslide monitoring measures were adopted timely, the effective forecast analytical calculations were put forward, and the good results of landslide preventive treatments were obtained. They are valuable as reference for the similar engineering works.
