| 摘 要： | 龙滩水电站导流隧洞进水口结构属于典型的非杆件体系水工混凝土结构，较为合理的设计方法是采用钢筋混凝土非线性有限元法进行配筋设计。采用空间非线性有限元方法对进水口中墩结构进行分析后认为：原有的配筋方案基本能满足结构承载力要求；在基本计算中分缝的影响可以不计；在闸门孔口附近应采取适当的防水措施；对中墩前部和尾部可以优化配筋方案。

| Abstract: | The hydraulic intake of diversion tunnel of Longtan Hydropower Station is a non-member system and typically hydraulic concrete structure. It is reasonable to design the reinforcement with nonlinear reinforced concrete finite element method(FEM). Three-dimensional FEM is applied to analyze the middle abutment of diversion tunnel. Several suggestions have been made: the original reinforcement can meet the requirement of the structural capacity; the gap between the middle abutment and the rock can be ignored in the basic computation; waterproof measures should be taken near the gate hole; the reinforcement in the front and the rear of the middle abutment can be optimized. |
