结合赵山渡引水枢纽沙门渡槽工程实例,分析渡槽裂缝的分布特点,利用应用软件建立矩形混凝土渡槽的三维有限元模型,对不同工况下渡槽受力状态进行数值模拟。从自然环境、工程建设标准、施工条件和主要结构部位等方面,讨论裂缝形成原因,为裂缝处理提供参考。
Combined with the project example of Shamen aqueduct at Zhaoshandu water diversion project, the distribution characteristics of aqueduct cracks are analyzed. The three-dimensional finite element model of rectangular aqueduct is established by using software to simulate the stress state of aqueduct under different conditions. From the aspects of natural environment, construction standards, construction conditions and main structural parts, the reasons for the formation of cracks are discussed to provide references for crack treatment.
