摘要:The integrity of arch dam can be obtained after the contraction joints are grouted.The mortar in the joints is able to bear the tensile stresses below the tensile strength.Moreover,the constraints of sphere or trapezoidal shear keys in tangential direction will vary with the opening of the joints.In this paper,based on the contact model represented by the B-differential Equations,an updated model is proposed in which the initial tensile strength and relationship between shear strength of shear key and joint opening is taken into consideration.Numerical example shows that the tensile stresses can be transferred between adjacent dam monoliths through joints,and the shear keys can provide large tancgential constraints even if the joints open.
