摘要
简支梁桥在新疆是一种广泛应用的桥型之一。采用数值方法分析了桥面破损对桥梁动力响应及冲击系数的影响。研究结果表明:车辆对桥梁的冲击作用随着桥面的破损的加重而增大。
The simply supported beam bridge is widely applicable in XinJiang.The effects of bridge deck damage on impact factor were studied by numerical method.The results show that the vehicles impact on the bridges increases obviously with the deterioration of bridge deck damage.
