Abstract:

ShenzhenGuangzhouZhongshan Fixed Link is a project determined by the State Council, which has great significance on the future development of Nansha, Guangzhou and the Pear River Delta. The project also has great influence on the economy, society, national defense, water conservancy, navigation, etc.. Furthermore, the project has great capital investment. Therefore, great attention must be paid to the plan selection of the project so as to achieve the optimum proposal. In the paper, comparison and contrast is made between the “east tunnel + west bridge” proposal and the “only tunnel” proposal in terms of ship development trend, regional economy development needs, national defense requirements, water environment influence and technology. It is concluded that the “east tunnel + west bridge” proposal is irrational, which may cause enormous strategic loss and may result in historic regret. Furthermore, 3 advices are made as follows: 1) The “only tunnel” proposal, which is feasible, is recommended; 2) If there is still doubt on the “only tunnel” proposal, it is recommended that the length of the tunnel can be shortened to only cross underneath the main course of Guangzhou Harbor by referring to the navigation standard of HongKongZhuhaiMacao Bridge Project; 3) The disputes should be suspended, the comparison and contrast should be continued before the final decision to commence the project is made.
