Abstract：Research purposes: Xiamen Xiang' an Submarine Tunnel is the first submarine tunnel in Chinese continent and a milestone in Chinese history of tunnel construction, with complicated geological conditions. The summary is made in this paper for the application of technologies of geological forecast in advance in construction of submarine tunnel for the purpose of providing the important basis for working out the construction program, speeding up the construction progress and ensuring construction security.
Research methods: Based on the many technologies of geological forecast in advance used in construction of A3 bidding section of Xiamen Xiang'an Submarine Tunnel, the explanation is given to the optional principles of the means and methods of geological forecast under different geological conditions.
Research results: The work of geological forecast is well done and the geological conditions are made clear according to the principle of” Using different technology to the different rock".
Research conclusions: The integrated geological forecast can 6e done and the distribution of sand layer and water content within 100 m range in front of the working face and the distribution of underground water within 15-30 m range in front of the working face can be made clear by adopting the technologies of TSP202 geological forecast in advance instrument , drilling hole in advance , infrared detecting water and geological sketch.
