The main contents of this paper are as follows: Through the analysis and comparison, it is concluded that the use of immersed tunnels in the middle and lower reaches of the Yangtze River has more advantages than using bridges or shield tunnels. Objection to the bridge construction heat across the Yangtze River is proposed. Many bridges The bridge is difficult to be standardized and will have an extremely adverse impact on the shipping of the Yangtze River. It briefly introduces the general situation of the immersion pipe technology in our country and the world, and reviews the current doubts about the construction of the immersed tunnel under the Yangtze River.
