Blender在“灾害学”课程教学与学生科创中的应用与实践

Blender in Disaster Science Teaching and Students′ Scientific Innovation

“灾害学”课程是防灾减灾科学与工程专业必修课,其主要目标是使学生掌握典型灾害的致灾机理、发展演化过程等。基于上述背景,以泥石流灾害场景为例,开展了典型地质灾害的可视化仿真研究。首先利用Blender软件和GIS辅助插件,搭建了典型灾害场景快速仿真与分析平台,实现了对泥石流灾害场景的快速构建;然后利用Blender中的粒子系统实现了对暴雨环境的模拟,并通过设置不同的域参量,实现了对洪涝、泥石流和滑坡等次生灾害的模拟;最后以郑州“7·20”特大暴雨为例,验证了暴雨灾害仿真的可行性。

This paper conducts a visualized simulation study on typical geological disasters,taking the scenario of a debris flow disaster as an example.Firstly,a rapid simulation and analysis platform for typical disaster scenarios was constructed 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.
