摘要
棉花滩水电站尾水岔管采用钢筋混凝土管,尺寸较大,两岔管相距较近。地下钢筋混凝土岔管与围岩联合工作,受力状况较为复杂。通过对钢筋混凝土岔管和围岩在内水压力或外水压力作用下采用三维非线性有限元的分析,了解岔管在各种工作情况时的受力状况,从而进行正确的设计。
The draft bifurcated tube in Mianhuatan hydropower station is the reinforced pipe. Its dimension is bigand the distance between two bifurcated tubes is small. The underground reinforced concrete bifurcated tube and theadjoining rock jointly works. The stressing is complex and it is analyzed by the three - dimensional non - linear finiteelement method under the internal water pressure and the external water pressure for the correct design.
