Abstract The catastrophic behavior of working face，the movement and development of debris flow，the stability control of the surrounding rock mass are the key scientific issues of tunnel construction in the debris flow strata. A test device capable of simulating the geological structural features of Qilianshan tunnel were developed for investigating the occurrence，the development and the mechanism of catastrophe of debris flow. A program of orthogonal tests was carried out to study the effects of the water pressure，the debris gravity and burial depths of debris strata，material compositions on the occurrence of debris flow. The instability model of tunnel face and the stability identification index of tunnel face under the lasting action of water pressure were investigated. The conditions of strata formation of debris flow such as the material structure，the groundwater and the tunnel excavation section were analyzed systematically according to the results of the model tests.

Key words： tunnelling engineering debris flow strata catastrophe behavior orthogonal test tunnel face stability
