| Summary: | 碩士 === 國立中央大學 === 土木工程研究所 === 88 === Most rivers in Taiwan are severely degrading during last two decades due to fast growing in-stream sand mining and construction of water supply or diversion works. Consequently, the exposure of bridge foundations, such as caissons and piles of bridge piers , is one of the most critical issue for the design and maintenance of river-crossing bridges. Inadequate design of countermeasures at bridge crossings may incur further local and contraction scours. The scouring process, such as maximum scour depth and scour dept and scour depth and scour range, around non-uniform piers and pile foundations are examined in this study by employing laboratory experiments . The suitable countermeasures for those foundations will is also investigated
