摘要
利用ANSYS有限元分析软件计算分析了四种连续类型简支梁桥支座处桥面开裂问题,得出了四种类型简支梁桥桥面混凝土的裂缝展开特点,比较说明了先简支后连续(用预应力筋使结构连续)桥型的优越性。
Using the finite element analyse software ANSYS, this paper calculated and analysed four kinds of problems about the pavement cracking on the pier of the simply supported bridge. Comparing the four kinds characteristic of the pavement concrete cracking, this paper get the result that the continued by prein forcing steel bar after simply supported bridge is preferably.
