| 摘 要： | 文章采用正态动床概化模拟试验方法,对跨江大桥主桥墩周围的局部冲刷问题进行了试验研究。试验结果表明,冲刷坑的深度和范围与床面的地质条件、水深、流速、墩宽和墩形有密切关系。试验得出局部冲刷与流量的关系和最大冲刷深度,并提出了桥墩局部冲刷的防护措施。

| Abstract: | In the paper,a simulation experiment of generalized normal movable bed was conducted to investigate the local scour cross the river bridge pier.The results of study show that the depth and scope of the scour hole have a close relationship with the bed surface geological conditions,water depth,velocity,width and shape of the pier.In addition,the relationship between local scour and flow,and the maximum scour depth have been concluded,and the protective measures of local scour have been proposed as well. |
