南阳回龙抽水蓄能电站尾水洞加固灌浆施工过程及三维有限元计算

Process and Calculation of the Reinforcement of the Tail Water Tunnel of Nanyang Huilong Power Station

详述了南阳回龙抽水蓄能电站尾水洞加固灌浆的施工过程,并采用大型有限元分析软件ANSYS,对加固过程中的钢板内衬的强度、刚度及稳定性进行了验算,结果表明:加固过程采用的技术较为可靠,加固后的尾水洞能够满足正常使用的要求.

This article relates in detail the process of reinforcement of the tail water tunnel of Nanyang huilong power planty. By means of large - scale finite element analysis software ANSYS, the intensity, the rigidity and the stability of steel plate inside in the process has been calculated. The technology adopted in the reinforcement process is proved reliable and the reinforceed tail water tunnel can satisfy the request of normal use.
