Abstract:
The modification of design and construction of tunnel can be realized by adopting informatization construction. In this paper: 1) The information, i.e. stability of working face, variation of surrounding rocks, deformation/convergence of supported section and surrounding rock classification, is the base of informatization construction. The quantity of the information is the base and the quality of the information is the key. Case studies are made on deformation monitoring and Database of Mining Method in Japan. The informatization construction in China still needs to be optimized in terms of quality of information. 2) The methods and purposes of information are introduced in terms of detection of surrounding rocks, observation of working face, measuring and test. The application of advanced borehole drilling method to geological detection of Hokkaido Highway Tunnel and Chikushi Tunnel in Japan is introduced in detail. 3) The contents, methods and stateoftheart of working face observation in China, Japan and USA are introduced. The quantization of information collected in China still needs to be developed. The items to be checked and observed and using of observation results of shotcrete are introduced. 4) The information collecting methods for different surrounding rocks vary much. The observation is the most important in collecting information in rocky surrounding; and the observation, measuring and prediction should be carried out in collecting information in soft and weak surrounding rocks.
Key words: tunnel, informatization construction, observation, measurement, quantization, database
