2、和漂距影響的經(jīng)驗公式,分析了N與V級航道橫向流速的限值范圍。分析結(jié)果表明:橫流對船舶航行的影響程度主要與對岸航速成反比,與橫流的大小及區(qū)域長度成正比,與船型大小(航道等級)成反比,同時與駕駛員的航行經(jīng)驗和初始船位有關;在限制航路航行方式過程中,W與V級航道對岸航速為2,3,4m"s-’時,可克服的一個船長內(nèi)橫流限值為0.48,0.58,0.70m"s-1,關鍵詞:航道工程;內(nèi)河航道;橫流;船模試驗;橫流限值中圖分類號:U611文獻標識碼:AInfluenceofcrosscurrentonshipnavigationininlandwat
