甘孜州巴塘至白玉公路树葬滑坡的稳定性分析和治理措施

摘要

Shuzang Landslide along Batang—Baiyu Highway in Ganzi,located on the right slope in the section of K66 + 640 ～ + 608,is a middle-sized medium cumulate retrogressive engineering active landslide,which endangers the operation of highway seriously.Therefore,on the principle of economics,applicability and security,the scheme of framework anchor cable plus inner retaining support bolt,was selected by means of stability analysis and multiple schemes comparison.Now there have passed two rainy seasons after the construction,and the monitoring data shows that,the deformation of landslide is negligible and the control measures are successful,within the controllable range.%甘孜州巴塘至白玉公路树葬滑坡,位于巴白路K66+ 640 ～+608右侧边坡,为中型牵引式中层堆积层工程活滑坡,严重威胁公路的正常运营.本着经济、适用、安全的原则,在稳定性分析的基础上,进行了处治的多方案比选,采用了“框架锚索+内挡垫墩锚杆”方案.施工结束已历经两个雨季,监测表明,滑体变形很小,在可控范围内,治理措施是成功的.
