摘要
当前,在我国西部高山峡谷地区修建了许多大型水电工程,高压引水隧洞结构也得到广泛应用。但由于水工高压引水隧洞的环境条件和工作机理复杂,在隧洞衬砌开裂后的裂缝间距与宽度、高压内水外渗及水荷载、计算分析方法等方面,仍然存在不少问题没有得到很好的解决。在对这些问题的研究现状进行总结分析的基础上,指出需要进一步研究的课题。
Deep tunnel is a kind of structure widely used to huge hydraulic projects built in west of china. Although it possesses several particular advantages, many problems has not been successfully solved due to the complexity of its working environment and mechanism, such as quantitative analysis on the width and spacing of cracking of tunnel liner, the seepage load induced by the seepage from pressure tunnel and the selection of computation method. In this paper, the state of art of studies on the existing problems is summed up, and scientific issues on deep tunnels needed further research are pointed out at the same time.
