隧洞位置对拱坝应力和位移的影响

The impact of the location of the tunnel on the stress and displacement of the arch dam

本文基于有限单元法,利用ANSYS软件计算和分析,总结出水工隧洞在不同位置的一些变化规律,希望这些结论能为今后的中、小型拱坝设计,施工中遇到坝肩山体开挖孔洞的情况及在拱坝后期的安全评价、维修加固过程中,为实际工程的修建和整治提供一个比较实用的理论依据与参考。

Based on the finite element method using ANSYS software to calculate and analyze,this paper summarize some various law of the hydraulic tunnel in a number of different position,which conclusion will provide a theoretical basis and practical reference for the small-sized dam design and construction which would experience to dig abutment in mountain,and in the case of the latter safety evaluation and maintenance and reinforcement process,the actual construction and renovation project.
