| 中文摘要: |
| 桥梁的基底位于河流之中，常年受到水流的冲刷，从而使基底面积不断减小，对桥梁结构产生不良影响．本文针对这一情况进行了研究．考虑到水流冲刷作用是发生于基底的各个方向上，且在不同方向上的冲刷程度不同．本文为更好的模拟实际情况。将淘蚀后的基底考虑成一偏心椭圆．在此基础上推导出淘蚀后基础抗倾覆系数的计算公式 |
| 英文摘要: |
| The basement of bridge located in the rivers,year after year,receives the influence of the water's washing out,thus unceasingly reducing the basis,and having no good effects on the bridge structure.This article has conducted the research in this situation.Considering the current of water washing out effect in basis from each direction,and different degrees of water washing out effect in the different directions,in order to better simulate the actual situation,this article argues that the shape of the basis was washed out to be an eccentric ellipse.Based on it,we calculated the coefficient formula of the basis antiverturning after water washing out. |
