Abstract

The experiments on the countermeasures of scours around pier in steady current were conducted in this paper. The factor formations of scour were identified by extensive research of previous paper that related to the project. Scour formations were influence by the strength of the flow, the size of pier, and the sediment condition. From the literature, the project invented a few innovative pier protection measures which are single cross-threaded pier and double-cross threaded pier with variation of cable diameter and thread angle. These cross-threaded piers also tested with collar protection. As the result, the single cross-threaded piers and double cross-threaded piers able to reduce scour in average of 18% and 21% respectively. While, single cross-threaded piers with collar and double cross-threaded piers with collar able to reduce scour in average of 69% and 63% respectively. The single cross-thread pier with collar of 0.1 cable-pier diameter ratio and 15° thread angle outperforms other models with scour reduction of 79%. That shows the cable-pier diameter ratio and thread angle influent the performance of models in scour reduction. The large number of cross-threaded pier with large cable-pier diameter ratio and small thread angle will give the best performance in reducing potential formation of scour depth.
