N2 - This paper presents the work on investigating the damage buildings including burying and collapse under debris flow, on the basis of investigation in Sanyan Valley. The impact load of debris flow is simplified into triangular impulse load, rectangular impulse load and spike impulse load, through theoretical derivation, the results show that: when the ratio of impulse duration to natural vibration period of building β is less than 0.15, for spike impulse load, the displacement response ratio Rmax is much larger than 2, especially when the β is less than 0.02. While β is more than 0.15, for all of three impulse load, Rmax is less than or equal to 2, the maximum displacement amplitude vmax only depends on the magnitude of impulse load, thus it is recommended to set the displacement response ratio Rmax = 2 to estimate the maximum impact load, which could provide reference for future engineering design.
