基于动态地形模型的重大地质灾害仿真研究

Simulation of major geological disasters based on dynamic terrain model

地质灾害仿真有利于灾害发生时相关人员及时作出响应,降低地质灾害的影响。传统地质灾害仿真方法仿真效果不理想,导致重大地质灾害仿真的实用性较差。为此,提出基于动态地形模型的重大地质灾害仿真。对获取的地质灾害数据进行粗差检验、差值处理,保留地质灾害数据中原始数据,将地质灾害避难路径的获取归纳为图形最短路径的求解;设计重大地质灾害的仿真流程,完成重大地质灾害的仿真。实验结果表明,所提仿真方法在受伤人员相对生存概率、受伤人员的救出比例以及平均救援时间方面具有一定优势,验证了所提方法具有一定实用性。

Geological disaster simulation is significant to relevant personnel to respond in time when disasters occur and reduce the damage of geological disasters.The results of traditional geological disaster simulation were not ideal,which leads to poor practicability in this field.For this reason,a major geological disaster simulation based on dynamic terrain model is proposed.Perform gross error inspection and difference processing on the acquired geological disaster data,and retain the original data from the geological disaster data.Next,it would acquire the geological disaster refuge path from sumerization of the solution of the shortest path in the graph;design the simulation process of major geological disasters to complete major geological disaster simulation.Experiment results show that the proposed simulation method has certain advantages in terms of the relative survival probability of injured persons,and the rescue ratio of injured persons and the average rescue time,which verifies that the proposed method has certain practicability.
