在设计拦河坝时,如果能将坝基开挖成略向上游倾斜的坡度,就能提高其抗滑稳定性,这是熟知的事。但是坝基向上游倾斜的角度如何控制,还是值得探索的一个问题。本文根据重力坝断面的各种受力条件,推导出在满库情况下坝基向上游的倾角与坝体断面相互关系的计算公式,以供设计参考。 It is a well-known fact that in the design of a dam, the stability of the anti-sliding can be improved if the dam foundation can be excavated into a slightly sloped slope. However, how to control the angle of the dam foundation to the upstream is still an issue worth exploring. According to various stress conditions of gravity dam section, the formula for calculating the relationship between dam dipping angle and dam dipping angle under full reservoir condition is deduced for design reference.
