| 摘 要： | 到目前为止,水电站高压引水隧洞灌浆预应力抗裂设计还没有详细的计算方法。为此,结合某水电站引水隧洞设计,采用有限元法,比较了非正常工况下不同衬砌厚度时衬砌的变形和应力状态,得出衬砌厚度为40~50 cm时较为合理。

| Abstract: | At present,anti-crack design for pre-stressed grouting of hydropower high-pressure diversion tunnel has no detailed calculation methods.For the design of a diversion tunnel,the deformations and stresses of lining with different thickness and in non-normal operating conditions are studied herein with finite element method,and the result shows that the lining thickness of 40 ~ 50 cm is more reasonable. |
