摘要
某工程的渡槽结构,因跨度较大而采用预应力混凝土结构。笔者采用三维有限元仿真模拟技术分析了混凝土渡槽结构应力和变形,计算结果证明该结构采用预应力合理、有效地控制了混凝土渡槽结构拉应力。
For the aqueduct of a project,pre-stressed reinforced concrete structure is adopted due to large span.The author analyzes the structural stress and deformation of the reinforced concrete aqueduct by use of 3-D finite element simulation techniques.The results of calculation show that the pre-stress used for the structure is rational,and the structural tensile stress of the reinforced concrete aqueduct is effectively controlled.
