It's very important to simulate impact load of debris flow ef-fectively and to investigate dynamic response of architectures under dy-namic impact of debris flow,which are necessary to design disaster miti-gation construction. Firstly,reinforced concrete domestic architectures in mountain areas of western China had been chosen as main architecture style. The bearing load style and the destructed shape of reinforced framed construction impacted by discontinuous viscous debris flow were studied systematically. Secondly,Jiangjia Ravine debris flow valley in Yunnan Province,China had been chosen as research region. Utilizing based data from fieldwork and practical survey,the authors simulated and calculated theoretically impact force of discontinuous viscous debris flow. Thirdly,an impact data collecting system(IMHE IDCS) was designed and developed to fulfill designed simulation experiments. Finally,a series of impact test of researched structure models had been fulfilled. During experiment,the destructed shape and course of models were observed and the dynamic displacement data and main natural frequency data of models were col-lected and analyzed.
