Study on the Joint Open Deformation Using Joint Interface Element in the Shiplock of the Three Gorges Project

Abstract:

In light of the open deformation of joints in the middle isolated pier of the permanent shiplocks of Three Gorges Project(TGP), a typically simplified joint model is set up based on the geological conditions and the crack investigation. The method of joint interface element is used to analyze the joint open deformation and study the characteristic of open joints. The results show that the open deformation and the open length of joints are directly related to their occurrence and geometrical character.
