舟山跨海大桥桥上安全行车风速研究

Study on Safe Wind Velocity of Driving on Zhoushan Sea-cross Bridge

受大桥通航净空的限制,舟山跨海大桥桥面高程高、风速大以及桥梁本身的结构特点,使得车辆的行驶环境大为改变,影响行车安全。本文通过对不同速度下车辆所受风力及影响行车安全外力的综合分析研究,计算不同车速下跨海大桥上车辆的安全行车风速,为跨海大桥运营期限速指标的确定提供理论分析依据。

Because of relevent headroom regulation, Zhaoshan Bridge has a high road surface where suffer speedy wind. Plus the characteristic of the bridge structure, the traffic condition on bridge is hard and it may cause safty problem. This book includes research targeting on the relationt between wind speed and the force working on vechicle and showing the maxium figure for vechicle running in different wind speed. The book provides a theoratical standard to deter- mine the driving speed to guide real operation.
