Abstract Focused on the current situation of the underground caverns and the key difficult problem of the information construction, a new method is put forward for the rapid analysis of the stress field of surrounding rock, which is based on the quantitative laws of the results of numerical tests under the main influence factors of the surrounding rock. Firstly, eight main influences of the stress field of the surrounding rock without fault were pointed out which is based on the systems numerical testing. Then, a Fast Analysis System for the Tunnels(FAST) without fault is build which is based upon lots of numerical test results，measured data, expertise and the powerful artificial neural network method. Further more, the FAST with one fault or two were established separately, which is benefited from the influence coefficient of deformation from fault that was introduced by our research group years ago and greatly reduce the number of the numerical experiments. After comprehension of these three FASTs and the fast inverse analysis system and the fast evaluation system, a fast intellectual analysis and evaluation system is established based on the mixed programming techniques of VB and FORTRAN. Several practical engineering applications have showed a good reliability and applicability of the system.

Key words： information construction tunnel fast automatic artificial neural network structural plane
