Discussion on Soil and Water Conservation Measures of Chongqing Fengyun Line of National Road

Based on analysis of characteristic and construction procedures of the expressway and compared with the filed survey data in other similar area, the scope of duty on prevention of soil erosion was well and truly designated. The effect and potential danger of landslide and debris flow was well-considered. Then soil and water conservation measures system of the expressway including prevention measures of principal part of building, new added measures and monitoring and prediction of landslide and debris flow were put forward.
