[Abstract]:Based on the field investigation of Hezhi ditch in Jingchuan County, Pingliang City, Gansu Province, this paper collects the data of meteorology, hydrogeology, engineering geology, levee construction and so on, and mainly studies the engineering measures and evaluation methods of mountain torrents disaster control in Hezigou. The aim is to provide theoretical basis and technical support for the construction of local mountain flood prevention and control project. The results of this study are as follows: (1) through collecting hydrology, geology, geomorphology and natural conditions of the study area, investigating the historical mountain torrents disaster, at the same time matching the runoff, flood, hydrogeology, stratigraphic lithology, sediment of Zhigou, Based on the analysis of river evolution and river facies, a safe, effective, scientific and reasonable mountain flood disaster control measure is worked out. (2) determine the width of the channel and the arrangement of the dike conductors, determine the form of the levee according to the actual situation of the study area, and then determine the height of the dike by the calculation of the water surface line, the top height of the embankment and the depth of erosion. The gravity retaining wall is put forward as the form of levee, and the stability calculation and seepage calculation are carried out, and the theoretical system of river course regulation research in mountain flood disaster control measures is established. (3) through the comprehensive analysis and research, the section size and dike form of each section of He-Zhi ditch are determined, and the river channel dredging is carried out to ensure the smooth flow of the river at the same time. (4) to divide the responsibility range of soil and water conservation in the river reach, and to evaluate the soil and water loss which may be caused in the course of control, and to explain the overall control measures of soil and water conservation and the monitoring and management of soil and water conservation; In the process of management, the environmental protection is carried out. According to the present environmental situation, the environmental impact is evaluated and the corresponding environmental protection measures are taken.
