【摘要】 通过引入当量长度的概念,构建了有组织疏散的城市避震疏散优化模型,并采用遗传算法(GA)实现了模型的优化求解;当量长度考虑了疏散环节各种影响因素,较之单纯采用道路长度作为疏散距离而言更有实际意义;最后以青岛市某次假设地震为例,在GIS平台下实现了对避震疏散方案的可视化表达。更多还原

【Abstract】 A seismic evacuation optimized model based on equivalent length is proposed and solution is achieved with Genetic Algorithm.Compared with the road length,the equivalent length which takes various evacuation factors into account holds more practical significance in terms of evacuation issue.At last,a seismic evacuation of a scenario earthquake in Qingdao is exhibited as a visual example based on GIS platform.更多还原
