Experimental apparatus and methods for scour of seams between tubes of punctured geotube dam

摘要: 为模拟波浪水流沿袋间接缝对侧壁损伤管袋坝的冲刷过程,自行设计了一套试验装置;该装置主要包括模拟管袋的砂箱、接缝管路、波浪水流发生器及信息采集设备;针对该装置提出了相关试验方法,包括试验材料和试验环节;最后,对该试验装置及试验方法的有效性进行了验证,证明该装置及方法可以完成不同条件的波浪水流沿袋间接缝对侧壁损伤管袋坝冲刷过程的模拟。

Abstract: To simulate the scour of punctured geotube dam along the seams between tubes under wave action, a set of experimental study apparatus is designed. The apparatus mainly includes wave generator, pipeline, sand box and information collecting device. The related methods are put forward, including experimental materials and processes. Finally, the effectiveness of the apparatus and methods is validated, and it is verified that the scouring process of punctured geotube dam in different waves can be simulated by the apparatus.
