摘要

在受限水域内，针对带DP（dynamic positioning）动力定位系统的自航式双体船拖带沉管浮运航道的尺度，现行规范中没有可参照的设计原则和依据。为解决工程中存在的航道设计类似问题，结合航行模拟和计算，在总结分析现有技术资料和航道设计方法的基础上，提出采用复式航道设计的理念，根据船型、航道地质情况、航速等技术参数进行综合分析和计算，并采用模拟航行的方式，建立复式航道的设计原则和方法，得出航道设计过程中的关键技术影响参数。采用复式航道可以保障沉管和船舶行驶安全，也可有效降低受限水域航道开挖的疏浚量，对生态和海洋环境的保护起到了积极促进作用，同时可以实现资源的有效利用，节约环保，达到了预期的设计和使用效果。

自航式双体船拖带沉管航道尺度分析研究:以深中通道沉管隧道为例

[J]. 隧道建设, 2020 , 40(6) : 840 -844 . DOI: 10.3973/j.issn.2096-4498.2020.06.009

Abstract

There is not any design principle and reference for channel dimensions for immersed tube element towed by selfpropelled catamaran with dynamic positioning(DP) system in restricted waters in current specifications. As a result, the existing technical data and channel design methods are summarized, and the design concept of compound channel is proposed based on navigation simulation and calculation. And then comprehensive analysis and calculation are carried out based on the technical parameters such as ship type, channel geology, navigational speed, etc., the design principles and methods for compound channel are established by means of simulated navigation, and the key technical parameters are obtained. By adopting compound channel, the safety of immersed tube and ship can be guaranteed, the dredging amount of waterway excavation in restricted waters can be effectively reduced, which help promoting the protection of ecology and marine environment; at the same time, the effective use of resources and economization and environmental protection can be realized.
