摘要
沙窝子高边坡位于国道317、213都江堰至汶川公路新建路段,通过对其工程地质条件(地形地貌、岩性、构造及水文地质条件等)的研究,将其划分为滑坡变形区、不稳定区、飞石区、较稳定区、崩积堆积区及稳定区6个分区,着重分析了对公路危害影响较大的滑坡区与飞石区,并针对性地给出清除滑体物质、削坡、喷锚支护、设置SNS被动防护网及坡面保护等工程治理措施。对同类型高边坡的治理有一定的参考价值。
The Shawozi slope lies in the side of Dujiangya-Wenchuan highway. By studying the geologic condition of Shawozi slope, six parts are divided in the area, they are the deformation area, unstable area, slungshot area, mid-steady area, collapse and accumulate area, steady area. It is emphatically analyzed the deformation and slungshot area, then the corresponding measures are made out to prevent and cure the damage of the Shawozi slope. It can be helpful in the design of the same kind of abrupt slope.
