针对预应力混凝土连续梁桥裂缝损坏问题,以佛山市某立交桥为工程背景,采用空间有限元方法,对两种维修加固方案下桥梁的受力状况进行对比研究,对两种方案的施工工艺和技术特点也进行了探讨。 Aimed at the crack damage of prestressed concrete continuous beam bridge, an overpass bridge in Foshan was taken as the engineering background. The spatial finite element method was used to compare the stress conditions of the bridges under two kinds of repair and reinforcement schemes. Technical characteristics have also been explored.
