Parameter Sensitivity Analysis of New Concrete-rockfill Combination Dam Based on Orthogonal Test Method
摘要
Abstract
Based on orthogonal test method, the sensitivity analysis model for the parameters of concrete-rockfill combination dam is built, and then the anti-sliding stability and anti-overturning stability of dam and the maximum horizontal displacement of concrete wall under the influences of different factors are systematically calculated. The calculation results are compared with a existing model, and the accuracy and reliability of model are verified. The results show that the top width and slope angle of concrete wall are the most significant geometric elements and its sensitivity are relatively larger on the anti-sliding stability, anti-overturning stability and concrete wall maximum horizontal displacement, and the height of concrete buttress has most significant effect on maximum horizontal displacement of concrete wall.关键词
