- 摘要:
- 采用水力模型试验的方法，针对典型工程，对桥墩周围河床的局部冲刷及拦沙坝的防护作用进行研究。初步研究表明，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非常明显。通过研究提出的采用拦沙坝防护的桥墩局部冲刷公式为浅基桥梁工程防护设计提供了参考依据。
- Abstract:
- Aimed at the representative project in the piers,which is protected by the downstream sediment storage dam,this paper has studied local scour in piers and defensive function of the sediment storage dam by means of hydraulic model tests.In primary conclusions,as a kind of protective measure,the sediment storage dam is feasible,which can control backward erosion near these bridges have no enough buried depth,and its function of alleviating scouring depth is very obvious based on the study.The formula of local scour depth near piers protected by the sediment storage dam,deduced from the paper,will provide references for practices.
