Anti-sliding safety prediction method for impact on shoreside retaining wall when bridge floor touch ground

The invention provides an anti-sliding safety prediction method for impact on shoreside retaining wall when a bridge floor touches the ground. The method comprises the following steps: determining a horizontal additional force generated in unit width of a wall back at the moment when the bridge floor touches the ground; determining soil pressure in unit width of the retaining wall; the anti-sliding safety coefficient SF of the retaining wall is determined; if the SF is greater than or equal to a set threshold value, judging that the retaining wall is in a stable state, otherwise, judging that the retaining wall slips and is damaged. The method has the advantages of being high in process, simple in structure and reliable in result. 本发明提供了一种桥面触地对岸边挡土墙冲击抗滑移安全性预测方法，包括步骤：确定桥面触地瞬间对墙背单位宽度内产生的水平附加力；确定挡土墙单位宽度内的土压力；确定挡土墙抗滑移的安全系数SF；若SF大于或等于设定的阈值，则判断挡土墙处于稳定状态，否则判断挡土墙出现滑移破坏。本发明具有流程性强、结构简单和结果可靠的优点。
