In order to study local scouring field near the pier with sediment control dam ,the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek.

采用Sontek公司声学多普勒测速仪对有拦沙坝防护的模型桥墩附近流场进行了精细测量，对桥墩冲刷坑内三维流速分布进行了分析，给出了冲刷坑内三维紊动特征量的分布，分析研究了有拦沙防护坝时桥墩局部冲刷的三个新特点，提出了拦沙坝的适用条件。

In order to study local scouring field near the pier with sediment control dam, the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek. This paper analyses the velocity distribution in the scouring pool of pier and takes turbulent strength distribution in different direction. Three new characters for the local scours of piers with the sediment control dam are analyzed and the dam's applicability is brought forward.
