大型雙體船碼頭防臺系泊帶纜受力計算預報研究

摘" " 要：船舶系纜力不僅受到風、浪、流等自然條件，還有船型、噸位、載重量等船舶自身因素以及纜繩材料、系纜方式及碼頭設施等一系列因素的影響。本文以模型船為例，通過對帶纜受力各輸入要素的研究，簡化建立某船模型，采用MOSES軟件進行數值計算。根據計算結果對某船碼頭防臺系泊帶纜受力進行分析預報，提出改進措施和注意事項，提高了碼頭防臺系泊帶纜安全性，可為其他船舶相應碼頭防臺系泊帶纜提供參考借鑒。

Abstract： The mooring force of a ship is not only influenced by natural conditions such as wind， waves and current， but also by the ship’s own factors such as ship type， tonnage and deadweight， as well as a series of factors such as cable materials， mooring methods and dock facilities. This paper takes the model ship as an example， simplifies the establishment of one ship model through the study of various input elements of the mooring line and uses MOSES software for numerical calculation. According to the calculation results， the mooring force of a ship’s wharf typhoon defence is analyzed and predicted， and the improvement measures and precautions are put forward to improve the safety of mooring cables for wharf typhoon defence， which would provide reference and inspiration for other ships’ corresponding dock anti typhoon mooring cables.

1" " 引言

對于在臺風影響下的船舶系泊模式，目前沒有規范可以參考。南方地區夏季臺風多發，破壞力強，針對大型雙體船干舷高、上建側投影面積大、受風面積大， 通過對大型雙體船碼頭建造階段的防臺系泊模式研究，確保臺風來襲時船舶的系泊安全。為此，本文在分析我司碼頭平面布置及風、浪、流、潮汐等因素的基礎上，提出采用Moses數值計算軟件，應用“準靜態”方法，計算系泊帶纜受力。研究所獲的數值計算結果，可用于我司碼頭系泊大型雙體船防臺工作參考。

2" " "帶纜受力分析各輸入要素研究

由于船舶帶纜受力不僅受到風、浪、流等自然條件的影響，還有船型、噸位、載重量等船舶自身因素以及纜繩材料、系纜方式及碼頭設施等一系列因素。先對影響帶纜受力的各輸入要素進行分析研究。

1）碼頭

防臺纜繩的布置需要確定碼頭及其帶纜樁，根據碼頭水深、帶纜樁布置及我司防臺經驗，選定某碼頭為系纜防臺碼頭，“L”型碼頭能提供更強的系纜力。……
