根据河口村水库1#泄洪洞与发电洞联合进口塔架的结构布置型式及运用要求,采用拟静力法、反应谱法有限元动力分析对联合进口塔架的整体稳定性进行了分析。同时,对稳定计算工况进行识别,补充完善规范相应计算公式;计算结果表明,联合进口塔架的结构布置体型合理,满足功能需求,进口塔架整体稳定性满足规范要求。
According to the structural layout and application requirements of the joint inlet tower of No 1 spillway tunnel and power generation hole in Hekou Village Reservoir, the overall stability of the joint inlet tower is analyzed by quasi-static method and response spectrum finite element method. At the same time, the steady calculation condition is identified and the corresponding calculation formulas are supplemented and improved. The calculation results show that the structure of the joint imported tower is reasonable and meets the functional requirements. The overall stability of the imported tower meets the requirements of the code.
