桥墩墩型对桥梁行车舒适度的影响分析

Analysis of the influence of types of pier to bridge on driving comfort

桥梁不仅要满足强度、稳定性等安全要求,还需要满足行人和车辆的舒适性要求要求,不同上下部结构类型的桥梁,其行车舒适性也不同。以一联4×40 m简支转连续刚构T梁及跨径组合为(65+120+65) m的连续刚构为例,在考虑车桥耦合的基础上,引入不同舒适度指标,研究不同墩型对简支转连续刚构T梁桥及变截面连续刚构桥梁行车舒适度的影响。

Bridges not only meet the safety requirements such as strength and stability,but also meet the requirements of comfort for pedestrians and vehicles. Different types of bridges have different driving comfort. This paper on the branches of the United 4 × 40 m turn continuous rigid frame bridge T beam and the combination of span（ 65 ＋ 120 ＋ 65） m continuous rigid frame as an example,in considering the basis of vehicle bridge coupling,the introduction of different comfort index,the study of different types of piers for simply supported turn influence to the comfort index of T beam bridge and variable cross section continuous rigid frame.
