| 摘 要： | 结合拟建江津中渡长江大桥桥墩船撞力计算,对船舶撞击速度、角度的选取及影响进行了探讨;分别运用国内外现行的规范公式、经验公式及有限元模拟方法,对3 000 t、5 000 t级船舶撞击桥墩的碰撞力进行了计算对比。结果表明:我国现行公路和铁路规范公式计算结果偏小,美国AASHTO规范公式、修正沃辛公式与有限元计算结果基本一致。

| Abstract: | Based on ship impact calculation of ready-built Jiangjin Zhougdu Yangtze River Bridge,the effect and selection of ship impact speed and impact angle were discussed in the paper.Code formula,empirical formula and finite element simulation method were employed to calculate the impact force of 3000-t ship and 5000-t ship.The results demonstrated that calculation results of road and railway code formula were small.The U.S.AASHTO formula,modified Worthing formula and finite element results were in agreement. |
