摘要
对广东顺德西安亭大桥(旧桥)引桥中的16 m简支T梁进行工程案例分析,通过对横隔梁加固、铰接缝改为现浇刚接、增强桥面铺装与梁体的粘结等方式对桥梁进行维修加固,并对加固方式进行有限元模拟。经计算表明,T梁加固效果明显,承载能力显著提高。
The article analyzes the engineering case of 16-m simple-supported T-type beam in the approachbridge of Xianting Bridge(Old) in Shunde of Guangdong. The mode of changing the diaphragm beam reinforcement and hinged joint to the cast-in-situ rigid connection and strengthening the bonding of bridge deck pavement and beam body is used to maintain and reinforce the bridges. And the reinforcement mode is simulated by the finite element. The calculation shows that the reinforcement effect of T-type beam is obvious and the carrying capacity is remarkably improved.
