本文作者根据自己实际工作中的体会,综合援引了比较丰富的国内外有关工程的资料,针对导流隧洞设计中存在的若干问题,提出了自己的见解和建议,可供有关设计、施工单位参考。但文中有关确定洞底高程、绘制河道耐久性曲线、计算洞顶岩层厚度和外水压力、隧洞衬砌结构型式的选择及其不衬砌条件等方面的一些论点、建议和公式也还不够成熟、全面和完善,尚值得进一步商榷和探讨。此外,我国在导流隧洞的设计方面还有许多带有普遍性的问题,如隧洞的不衬砌、进水口的形式及高程、洞口岩层的厚度及削坡等均有待不断加以总结、提高,使之日臻丰富和完善。
Based on my experience in actual work, the author of this article has comprehensively quoted a wealth of information about engineering at home and abroad and put forward my own opinions and suggestions on some problems in the design of diversion tunnels, which can be used for reference by relevant design and construction units . However, there are some arguments in the article about determining the elevation of the bottom of the tunnel, drawing the curve of the durability of the riverway, calculating the thickness of the top of the tunnel and the pressure of the external water, the choice of the tunnel lining structure type and its non-lining conditions. The suggestions and formulas are not mature enough yet And perfect, it is worth further discussion and discussion. In addition, there are many common problems in the design of diversion tunnel in our country, such as the non-lining of the tunnel, the form and elevation of the water inlet, the thickness of the rock formation and the slope-cutting, etc., all need to be constantly summed up, Become more rich and perfect day by day.
