Geological condition is the important factors in study on tunnel excavating disaster inevitably. From the aeolotropy of hard rock of tunnel engineering region, the stress distribution of several kinds of fault to the water gushing of tunnel, the type of geology disaster involved in macrocharacter, main control factors, disaster mechanism and control strategy in tunnel excavating are studied systematically in this thesis.
