On July 19, 2019, a landslide occurred in Dongshan Town, Zhouqu County, Gansu Province. Nearly 3.92 × 10 6 m 3 of material suddenly lost stability and slid downhill. The sliding body piled up at the foot of the slope and blocked the river. Using the results of a field investigation, the engineering geological background of the Yahuokou landslide is presented in detail. A numerical method is presented to simulate the runout process of the sliding debris and its impact effect on building structures. The smoothed particle hydrodynamics (SPH)-finite element method (FEM) fluid–structure coupling method is implemented to simulate the landslide dynamic disaster process (the impact behavior for buildings). The sliding debris is simulated using the SPH method, and the building structures are simulated using FEM. The velocity variation trends and moving distances of the sliding body in different zones show different evolution characteristics. The landslide debris flow impacts the building, causing part of the structure to be completely destroyed and buried. Part of the broken wall structure moves forward under the impact of the landslide, with the first part of the affected wall unit moving the farthest; this is characterized by “impact collapse.” Studies of detritus flows are helpful to further analyze the disaster mechanisms of landslides, predict their disaster scope, and provide references for landslides with similar geological conditions in China.
