摘　　要：高寒冻土和粉砂性地层一直是新疆水利建设地质研究的难点,为确保铁门关市1号泄洪沟堤防工程安全建设,基于建设任务,在分析堤线区地质构造稳定性和地质条件的基础上,采用地质勘察、野外渗透试验法,对1号泄洪沟沿线地层渗漏性、冻胀性、边坡稳定性、地下水及土腐蚀性以及渠基土的渗透变形等进行探讨,得出沿线土层为冻胀性土,为强透水层,且对钢筋和混凝土均有一定的强腐蚀性,需采取相关措施予以解决,为1号防洪工程设计和建设提供了科学依据。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.
