This paper conducts a visualized simulation study on typical geological disasters,taking the scenario of a de-bris flow disaster as an example.Firstly,a rapid simulation and analysis platform for typical disaster scenarios was construct-ed using Blender software and GIS auxiliary plugins,enabling the rapid construction of debris flow disaster scenes.Then,the particle system in Blender was utilized to simulate the torrential rain environment,and by setting different domain parameters,the simulation of secondary disasters such as flooding,debris flow,and landslides was achieved.Finally,the feasibility of simulating rainstorm disasters was validated using the case of the extraordinary rainstorm in Zhengzhou on July 20th.
