| 摘 要： | 桥(闸)墩的局部冲刷是桥梁毁坏的主要原因之一,在桥(闸)墩上加环翼式挡板的能有效地防护局部冲刷。通过水工实验,量测墩(闸)周围冲坑深度和宽度。结果表明,加上环翼式挡板后可以有效减小冲坑深度。在水深20cm,冲坑深度最大能够减少60.7%,冲坑宽度最大能够减小64.7%。

| Abstract: | The pier scour is one of major reason of bridge's damage.It is effective that protecte bridge pier(Brake) with ring-wing baffle from local scouring.Based on laboratory hydraulic model test,the width and depth around pier(brake) scour was measured.The results showed that the scour depth can reduced substantially when the pier(brake) is added ring-waing baffle.In 20cm depth,the maximum depth of scour hole can be reduced 60.7%,and width can be reduced 64.7%. |
