海上公路桥梁工程施工用运输船稳定性分析——以宁波舟山港主通道(鱼山石化疏港公路)公路工程为例

Stability Analysis of Transport Ships Used in Offshore Highway and Bridge Engineering Construction:Taking the Ningbo Zhoushan Port Main Channel(Yushan Petrochemical Port Dredging Highway)Highway Project as an Example

本文以宁波舟山港主通道(鱼山石化疏港公路)公路工程为例,以润海88、君津达999、苏盐海8998驳船、劲旅168驳船等船舶为例,结合其工程内容,对运输船施工过程中的稳定性进行了分析。结果表明:经过验算润海88、君津达999运输船满足本标段预制墩身单船单次运输4节的要求;苏盐海8998、劲旅168运输船满足本标段70m预制单船单次运输1片的要求。在宁波舟山港主通道(鱼山石化疏港公路)公路工程—主通航孔桥北侧70m跨径非通航孔桥施工过程中,进行了应用,均有效地保障了运输船的稳定性。研究可以为相似工程提供借鉴。

This article takes the highway project of the main channel of Ningbo Zhoushan Port(Yushan Petrochemical Port Dredging Highway)as an example and takes ships such as Runhai 88,Junjinda 999,Suyanhai 8998 barge,and Jinlv 168 barge as examples.Based on their engineering content,the stability of transport ships during construction is analyzed.The results show that after verification,the Runhai 88 and Junjinda 999 transport ships meet the requirements of four sections for single ship single transportation of prefabricated pier bodies in this section;The Suyanhai 8998 and Jinlv 168 transport ships meet the requirement of transporting one piece per 70m prefabricated single ship in this section.During the construction process of the main channel(Yushan Petrochemical Port Dredging Highway)highway project in Ningbo Zhoushan Port-a 70m span non-navigable bridge on the north side of the main navigable bridge,the application effectively ensured the stability of transport ships.
