The maximum strength of the rock reaches 216 MPa. The construction of a key technical system for the construction of a large -diameter shield tunnel in the intensity zone will play a demonstration role in the construction of China's tunnel in the future. "

The opening of the Shantou Bay Tunnel opened the sea and new channels for the whole weather for the north and south sides of the Bay of Shantou, which greatly shortened the two sides of the strait from 40 minutes to 10 minutes.
