Abstract:

It is recommended that comprehensive fuzzy evaluation method should be used in the geology forecast of tunnel works so as to make full use of all kinds of geology forecast methods and draw a relatively correct conclusion. The application of comprehensive fuzzy evaluation method in the geology forecast of tunnel works is presented in terms of the establishment of the factor set and evaluation set and the obtaining of the relative weight of the various factors on basis of engineering cases. The engineering practice verifies that the evaluation method is feasible.

Key words: comprehensive fuzzy evaluation method, tunnel, geology forecast, water bearing of rock mass
