坝高超200 m土石坝坝坡稳定风险控制标准
Research on Slope Stability Risk Control Standards for 300 m High Earth and Rockfill Dam
摘要
Abstract
With the development of earth and rockfill dams construct technology, earth and rockfill dams have built higher and higher, high earth and rockfill dam design has been used design specifications which only apply to the construction of 200m below and the design specifi⁃cation of earth and rockfill dam needs to be improved. For high earth and rockfill dam, it calculated earth and rockfill dam slope stability safety factor under different dam heights and different slope ratios based on the ratio safety margin and made slope stability safety factor change variation of high earth and rockfill dam clear. This paper took allowed slope stability reliable indicator of high earth and rockfill dam of 4. 2 as design standard, calculated the ratio safety margin of traditional method and reliability method and conducted linear regression. The re⁃sult shows that the slope stability safety factor of high earth and rockfill dams slide stability safety factor of 1.6 is on the same level with relia⁃bility 4.2 under normal conditions. Practical construction of high earth and rockfill dams proves the safety factor 1.6 is correct and reasonable.关键词
