Analysis on Cracking Mechanism and Numerical Calculation of Thin-Wall-Wide Pier

摘要：

The thin-wall-wide pier is a special structural style of Wuhan TianXingZhou Bridges infrastructure. Because of the shrinkage disaccord and the rigid connection between the pier and the footing, its easy to produce the vertical impenetrating cracks in the lower part of the piers during the process of the construction. In this paper, FEM is used for acquiring the temperature-stress distribution in the earlier period of the casting and clarifying the cracking mechanism inside this kind of pier.
