摘要
自然灾害会对城市的建设和人们生活产生巨大负面影响,但是传统城市规划方案抵御自然灾害的能力较低,为此构建一个考虑自然灾害约束的城市规划模型。设定城市规划流程,依照流程明确明确城市规划条件,分析城市灾害风险和防灾能力,通过分析结果对城市规划进行设计,实现考虑自然灾害约束的城市规划模型构建。为保证设计有效性,进行仿真试验,试验结果表明,考虑自然灾害约束的城市规划模型比传统城市规划模型自然灾害损害程度降低35%左右,虽然随着灾害程度的严重程度增加,城市规划模型所能起到的效果有所减弱,但与传统方法相比始终占据优势,说明所提方法具有可行性。
Natural disasters have a great negative impact on urban construction and people's lives,but the traditional urban planning scheme has a low ability to withstand natural disasters. Set up the process of urban planning,according to the process clear urban planning conditions,analyze the risk of urban disasters and disaster prevention capacity,through the analysis of the results of urban planning design,to achieve the constraints of natural disasters in urban planning model. In order to ensure the validity of the design,the simulation experiment is carried out. The results show that the damage degree of the urban planning model considering natural disaster constraints is about 35% lower than that of the traditional urban planning model. Although the effect of the urban planning model is weakened with the increase of the disaster severity,the effect of the urban planning model is weakened with the traditional urban planning model. The method is comparablly feasible.
