| 摘 要： | 针对典型工程采用水力模型试验的方法对桥墩下游拦沙坝的稳定及防护作用进行了研究,实例表明,在桥墩下游修建拦沙坝作为遏制浅基桥梁附近河段溯源冲刷的工程防护形式是可行的,拦沙坝减缓桥墩附近局部冲刷的作用明显,提出的防护拦沙坝的形式、尺寸等参数为浅基桥梁工程防护设计提供了参考依据。 |
| 关 键 词： | 桥梁墩台 局部冲刷 拦沙坝 防护底坡 |

| Abstract: | This paper studies the stability and protective function of the downstream sediment control dam of the bridge pier for the representative project using hydraulic model tests.As a project protective measure for restraining reach backward erosion near the bridges with low foundations,the example shows that building sediment control dam along downstream bridge pier is feasible and its function of alleviating local scour is obvious.The proposed parameters of type and size for sediment control dam provide references for protective design of bridge project with low foundations. |
| Keywords: | bridge pie local scour sediment control dam defensive gradient |
