Geological Analysis of Dike Construction of No.1 Spillway Ditch in Tiemenguan City
Alpine frozen soil and silty sand stratum have always been the difficulties in the geological research of water conservancy construction in Xinjiang.In order to ensure the safety construction of No.1 flood discharge ditch embankment project in Tiemenguan City,based on the construction task,on the basis of analyzing the geological structure stability and geological conditions of the embankment line area,the geological survey and field penetration test method are used to discuss the leakage,frost heave,slope stability,groundwater and soil corrosion along the No.1 flood discharge ditch and the seepage deformation of the canal foundation soil.It is concluded that the soil layer along the line is frost heave soil,which is a strong permeable layer,and has certain strong corrosion to steel bar and concrete,which needs to be solved by relevant measures.It provides a scientific basis for the design and construction of No.1 flood control project.
