Title: In-depth study on effect of the induced slit at the heel of Xiaowan high arch dam
Abstract: Effect of the induced slit at the heel of Xiaowan high arch dam is discussed in this paper based on recent study results.A no-thickness contact element is presented to simulate the work state of structure slit, uniaxial equivalent tension softening model is adopted as the constitutive model of dam concrete.The whole model and sub-model are adopted to perform FEM analysis for different structure slit by setting altitude and different water pressure in slit.The computation results during operation period show that the tensile stress on dam heel is released.Random cracks may be avoided.Structure slit has little influence on the wholeness of dam.
