本研究旨在提升船模阻力試驗結果的準確度，同時探討阻塞效應跟淺水效應在船模試驗時的影響與修正。在成大拖航水槽的阻力試驗使用之鋼纜拖船由陳維揚(2014)建立，並且由吳政翰(2015)精進改良，增加可靠度與再現性。
在擁有試驗的再現性之後，考慮因為阻塞效應的影響，並參考ITTC建議做阻塞效應相關的修正，在現有的修正方法之中尋找一個適合的修正方式，並且精進與修改修正方式使其更適合成大拖航水槽。
本研究現ITTC(2011)所提供的三種方法中，Schuster法修正速度最適合成大拖航水槽，原因是其根據均勻流理論考慮到自由液面的影響與船體運動相似，本次研究又根據Schuster法與淺水效應，提出更進一步的修正方法，同時修正速度與阻力。

We improve the experimental techniques of main ship model test and promote the accuracy of results. We also do the researches on blockage effect and shallow water effect in ship model test and blockage correction. The steel cable method of resistance test was established by Chen (2014) and was improved for the reliability and repeatability by Wu (2015)
After having the high repeatability resistance test data, we can consider the wall effects. This thesis followed the ITTC recommendation to do the correction of blockage effect and find out the most suitable blockage correction for NCKU towing tank. The further research on modifying blockage correction for NCKU towing tank is needed.
In three different kinds of blockage correctors from ITTC (2011), Schuster’s method is more suitable for NCKU towing tank. Because Schuster’s method is based on mean flow theory, which considered free-surface effect. We also make progress on Schuster’s method and include shallow water effect to make new blockage corrector which comments both velocity and resistance.
