深圳港区跨海货运通道方案比选研究

Comparative Study on Cross-sea Freight Channel Scheme in Area of Shenzhen Port

摘要:

深圳市妈湾跨海通道蛇口—赤湾连接线工程是深圳港区跨海货运通道的一部分，建设条件复杂，为此开展多线位、多工法方案综合比选，以确定兼顾各方需求的优化方案。对工程的功能定位、港区货运需求、沿线用地情况及规划等因素进行了详细分析，对跨海货运快速路通道从选线、工法、设计方案逐层递进，进行多方案比选。综合考虑了地下空间充分利用、减少对港区用地占用，降低施工对疏港交通影响等因素，确定了项目的选线方案以及双管单层15 m盾构的工法和设计方案。成果为深圳市等港区货运通道的选线及设计方案提供借鉴。

Abstract:

Shekou-Chiwan Connection Line Project of Shenzhen Mawan Cross-sea Channel is a part of the cross-sea freight channel in the area of Shenzhen Port. The construction conditions are complex. Therefore, the schemes of multi-route position and multi-construction method are comprehensively compared and selected to determine the optimization scheme considering every demand. The functional orientation of the project, the freight demand of port area, the land conditions and planning along the route, and the other factors are analyzed in detail. The multi-scheme comparison for the cross-sea freight express channel is carried out from the route selection, construction method and design scheme. The factors of fully utilizing the underground space, reducing the land occupation in port area and reducing the influence of construction on port traffic are comprehensively considered. The route selection scheme, the construction method and design scheme of double-pipe single-layer 15-m shield of the project are determined. The results can provide the reference for the route selection and design scheme of freight channels in port areas in Shenzhen and other cities.
