摘　　要：文中针对钢筋混凝土简支T桥梁出现的典型病害,以挠度作为分析目标量,采用ABAQUS通用有限元软件模拟不同等级单一典型病害及多种病害同时作用对桥梁的影响,并进行相关性分析。研究表明竖向裂纹对桥梁的损伤最为明显,而且多种病害共同作用时对桥梁的损伤程度都要大于其单独对桥梁的影响程度的线性叠加。结合研究结果,提出桥梁维护和使用过程中应注意的一些问题。Based on the typical faults of reinforced concrete T-shaped free beam,the paper introduced a method of using the general finite element analysis software ABAQUS as the tool to simulate the effect of bridge under single typical fault or many faults with the deflection as the target amount.The analytical results show that the damage caused by the vertical cracks on the bridge is most obvious,and the damage of the bridge caused by many faults is bigger than the sum of each kinds of faults.Combined with the research results,some problems about the maintenance and use of the bridge have been proposed,which should be paied much attention.
