地震带城市规划模型设计与仿真

Design and Simulation of a Model for Seismic Belt Urban Planning

摘要:

传统三维城市规划模型是利用三维技术通过计算机生成模型对城市进行规划，没有考虑城市地理位置因素，不能保障城市震后应急救灾工作效率。为此，构建一种新的地震带城市规划模型。通过对城市抗震防灾空间及防灾分区定义，并对其规划原则进行分析，从而为城市防灾空间规划提供依据；以此为基础，采用风险评估方法构建出地震带城市抗震防灾空间规划的基本模型。实验结果表明，所设计模型性能极佳，考虑到了城市地理因素，在进行城市规划的同时，能够促进城市震后应急救灾工作的高效运行。

Abstract:

Traditional three-dimensional urban planning utilizes three-dimensional technology with computer-generated models. It does not consider the geographical position of cities and cannot guarantee the efficient operation of emergency relief works after earthquakes. In this work, a new model for the planning of urban areas in seismic zones was constructed to address the limitations of traditional three-dimensional urban planning. The principle underlying disaster-prevention zoning and space planning was analyzed by defining urban seismic disaster-prevention space and zoning to provide a basis for urban disaster-prevention space planning. On this basis, the risk assessment method was used to construct the basic model of disaster-prevention space planning for urban areas in seismic zones. Experimental results showed that the designed model presented excellent performance and accounted for the geographical factors of the city. At the same time, the model can guarantee the efficient operation of emergency rescue work in cities after earthquakes.
