| Abstract: | Based on the heat conduction equation and stress increment equation,the HyperMesh software is applied to establish model of dock head by using 1~ 7d different pouring schemes.And temperature and stress fields of the first floor dock and platform pier within 0 ~ 90 d pouring are calculated with ABAQUS.Then the temperature field and stress curves are plotted and the most cracking area and time are obtained.Thus,a solution scheme is given and the optimal program is determined. |
