Abstract
Traditional earthquake rescue methods have many problems, such as the impact of road damage on earthquake rescue, the rational allocation of disaster relief materials, and the active division of rescue areas. According to the characteristics of earthquake relief, a new earthquake rescue model is designed from three aspects: high-altitude rescue, road transport relief supplies, and street human resources rescue. In this paper, the hierarchical Voronoi diagram is applied to the earthquake rescue problem, the earthquake rescue model is constructed, and the area affected by the earthquake is reasonably divided. We discussed the earthquake intensity and the proportion of the population in the disaster area and the number of disaster relief materials and other parameters and conducted an in-depth analysis of the model to form a useful earthquake rescue model. Visual simulation results have been obtained by computer simulation. Compared with the traditional earthquake rescue plan, the model proposed in this paper is more effective and scientific in improving the material distribution, personnel rescue, and postdisaster reconstruction after the earthquake, and it also provides a new idea for the rescue of other natural disasters. It has practical social value and broad application prospects. Besides, the models and conclusions given in this paper have been recognized by the Seismological Bureau of Hainan Province and the Mathematics Research Center of Hainan Province.
Highlights
Earthquake is a kind of natural phenomenon in which the Earth’s crust causes vibration and generates seismic waves during the rapid release of energy
The primary way of emergency response is to combine the mechanism of earthquake occurrence with the emergency plan [1]. e existing earthquake rescue model is categorized by two domains, including the disaster area and the actual rescue implemented since an earthquake happened. e significant issues of the utilization of traditional approach include the following: (1) the mathematical model used in the earthquake disaster is too simple [2]; (2) simple division of the postearthquake disaster area [3]; (3) it failed to consider the actual road damage situation of the earthquake-stricken village [4]
We have formed a new set of a hierarchical earthquake rescue plan with high-altitude exploration, road transport relief supplies, and personnel rescue. rough the computer simulation processes, considering the hierarchical disaster discrete points, the selection of isolated points and individual points, and the construction of hierarchical rescue solutions and models of Voronoi diagram, this earthquake rescue model can analyze the specific situation of the affected villages and Mathematical Problems in Engineering the urgency of disaster relief of the hierarchical disaster discrete points
Summary
Earthquake is a kind of natural phenomenon in which the Earth’s crust causes vibration and generates seismic waves during the rapid release of energy. Based on the specifications of the affected area, a feasible earthquake rescue model can be constructed by investigating the actual road damage level in a different area. According to the statistical data generated since the earthquake, this paper proposes the Construction of Earthquake Rescue Model Based on the Hierarchical Voronoi Diagram to simulate the rescue mode for this deadly earthquake. It will elaborate on some issues encountered in earthquake rescue to carry out the parameters in the model. A set of an auxiliary decision model for earthquake rescue is proposed, which is more efficient and convenient than traditional rescue methods
