Stress And Stability Analysis Of Inclined Layer RCC Gravity Dam

Inclined Concrete-spreading Method is the most effective, economical and speedy method when construction is in high temperature or rainy environment. On stress and sliding stability analysis of RCC dam, many valuable conclusions have been summed up. But to the RCC dam that is constructed with this construction method, how about the stress conditions and sliding stability are, there is still no summarized criterion. In such premise, based on the results of formers, a large amount of numerical calculation is done is this paper, in which adding lift interface element, changing elastic modulus of lift interface and throwing different water pressure to the dam are used. Based on a great deal of FEM numerical analysis and combining the sample of Jiangya water control project, the elementary analysis and discuss are included in the paper, some instructive conclusions to designing and constructing of engineering are also acquired.
