桥梁加宽就是在原桥梁的一侧(或两侧)新建桥梁或将原桥面一侧(或两侧)进行加宽,使行车道得到拓宽,从而满足交通需求。以某工程实例来分析桥梁加宽对原有桥梁承载力的影响,并得出一些相关结论。
Bridge widening is the construction of new bridges on one or both sides of the original bridge or the widening of one or both sides of the original deck to widen the carriageway to meet traffic needs. The influence of the bridge widening on the bearing capacity of the original bridge is analyzed by an engineering example, and some relevant conclusions are drawn.
