金沙江下游库区复建公路路基病害类型、成因与启示

Types,Reasons and Enlightenment of Subgrade Diseases of Reconstructed Highway in the Jinsha River Downstream Reservoir Area

在对金沙江下游溪洛渡和向家坝水电站库区复建公路路基病害调查的基础上,采用工程地质方法分析病害类型与成因,对筹建中的白鹤滩和乌东德水电站库区复建公路乃至金沙江流域其他复建公路工程有实际指导与建议的意义。对进一步为了解和加强防治金沙江流域库区复建公路路基病害提供理论支撑,并对指导金沙江流域库区公路复建具有重大实际意义。

Based on the investigation of the subgrade disease of the reconstruction of the Xiluodu and Xiangjiaba hydropower stations in the lower reaches of the Jinsha River,the engineering geological method was used to analyze the types and causes of the disease,which provide the reconstruction of the Baihetan and Wudongde Hydropower Station reservoir areas in the preparatory construction,even other reconstruction road projects in the Jinsha River Basin with practical guidance and recommendations.It provides theoretical support for further understanding and strengthening the prevention and control of highway subgrade diseases in the Jinsha River Basin,and has great practical significance for guiding the reconstruction of the Jinsha River.
