Analysis and Calculation of Ship's Impact Force in Quanzhou Houzhu Bridge Downstream

参照国内外已建桥梁撞击力的取值特点 ,分析比较我国铁路、公路规范与其他国家规范或指导公式对撞击力的计算结果 ,认为采用我国公路规范 。

Referring to the calculation characteristics of ship's impact force of built bridges both in China and abroad, and comparing the calculation results of impact force by railway or highway codes of China and by codes or directive formulae of foreign countries, it is concluded that by adopting China's highway codes and taking v in the formula as the absolute velocity, the calculation results conform relatively to the practical situations of this project.
