小江泥石流流域高速公路的选定线及高程控制

The Selected Route and Elevation Control of Xiaojiang Mud-flow Valley Highway

研究分析了区域内水文和泥石流对高速公路选定线的影响及评价。根据相关泥石流报告数据及沿线水文资料,确定泥石流区域路线的高程控制条件及计算方程式,推算泥石流淤积河床段路线高程,为泥石流区域高等级公路选定线及高程控制提供计算依据。

By collecting debris flow data in Xiaojiang river basin,the influence of hydrology and debris flow on selected highway lines in the region was studied and analyzed,and the evaluation was made.According to the related debris flow report data and hydrological data along the route,the elevation control conditions and calculation equations of the debris flow regional route were determined,the elevation of the route of debris flow silt bed section was calculated,and calculation basis for the selected route and elevation control of the high grade highway were provided in the debris flow region.
