浅析围堰抗滑稳定计算在老虎嘴水电站施工中的应用

Calculations of Cofferdam Stability Against Sliding in Construction

老虎嘴水电站上游围堰由于直接填筑在河床覆盖层上,坝身土石料配置较为简单,在确保抗滑稳定性能符合设计要求的情况下,达到了节约投资,缩短工期且安全的目的。通过对围堰抗滑稳定计算进行分析,为此类围堰施工积累了经验。

At Laohuzui hydropower station,upstream cofferdam is placed directly on overburden of riverbed,so earth and rockfill material placement in dam body is simple. This design meets requirements of stability against sliding,saving investment and shortening construction period and safety. The analysis on cofferdam stability against sliding provides references to the similar projects.
