查询词典 float bridge

The results show that side force, lift and overturning moment obtained by simulation and by wind tunnel test are consistent. When train travels with certain speed, the aerodynamic force and overturning moment acting on passenger car running on bridge, embankment and flat will increase greatly as cross-wind becomes larger while those increase less when the train runs on cut. Under the condition of strong cross-wind, aerodynamic force and overturning moment acting on train traveling on bridge are the largest. So the train traveling on bridge tends to overturn compared with that traveling on other three kinds of railway conditions. Aerodynamic force and moment acting on train traveling on cut are the least.

研究结果表明：侧向力、升力和倾覆力矩数值模拟结果与风洞实验结果均吻合较好；车速一定时，随着侧风速度的增大，列车在桥梁、路堤、平地上运行所受气动力和倾覆力矩均急剧增加，而在路堑上运行所受气动力及力矩增加缓慢；当侧风速度一定的情况下，客车在高桥上运行所受到的气动力及力矩最大，因此，强侧风下列车在高桥上运行较容易发生倾覆事故；在路堑上所受到的气动力相对最小。

Then, safety analysis method was constituted considered the typical damage of concrete beam bridge. 5. By amending the reduction rate of loading capacity used in Code for Maintenance of Highway Bridges and Culvers (JTG H11-2004), a new reliable index is presented in the same safety standard to reflect the relation between load and resistance. According to the basic principal of calibration method, the recommended gradation index was computed under various factors such as different load combinations, vehicle operating status and different failure modes. With these calculated numerical values, the calculated reliability indexes standard for the estimation of safety degree of in-service concrete girder bridge members was ultimately obtained.6. Based on the related standards and results on crack and displacement that cannot continue to loading at home and abroad, the evaluation grade of the concrete beam bridge is proposed by analogy.
