关于库区运营公路水库坍岸调查方法的探讨

Exploration on investigation method for reservoir bank collapse in operating highway of reservoir area

以澜沧江苗尾水电站库区沿江公路为例,采用卫星影像、三维实景模型辅助调查和现场调查验证分析的调查方法,为下一步抢险保通和永久性治理提供技术支持,保证公路路基稳定和运营安全。实践证明,对库区沿江公路水库坍岸地质问题的调查方法是切实可行、有效的,在澜沧江流域梯级电站库区运营公路水库坍岸地质问题的治理方面具有普遍性的指导意义。

Taking highway along Lancang River in Miaowei Hydropower reservoir area as an example,this article adopts a variety of investigation methods,such as satellites image,three-dimensions dioramas supplementary investigation,and verification and analysis basing on field investigation,in order to provide technical support for the next emergency traffic-keeping and permanent treatment,as well as to ensure the subgrades stability and safety of highway operation.Practice has proven that investigation methods for geological problems of bank collapse alongside highway in reservoir area are feasible and effective.There is no doubt that this article has universal guiding significance to treat geological problems of reservoir bank collapse alongside operation highway in Lancang River cascade hydropower station region.
