计算机技术在西部绿色城镇建设中的应用

本文针对西部绿色城镇建设中的地质灾害风险评估和早期预警、生态城镇规划与基础设施建设、绿色房屋结构体系等方面应用的计算机技术进行了总结归纳。在地质灾害风险评估和早期预警中,地理信息系统(GIS技术)通过与遥感技术结合,获得中国西部地区地质环境及大型地质灾害的基本资料,有利于西部绿色城镇建设中灾害监测和提早防治。在生态城镇规划与基础设施建设技术研究中,基于GIS技术的土方填挖分析和用地选择评价、基于Transcad技术的区域交通模拟、基于CFD技术的风环境模拟和基于众智软件的日照模拟逐渐得到了重视和应用。在绿色房屋结构体系研究中,计算机有限元数值分析方法和计算机并行计算技术已在土木工程结构体系抗震性能分析中发挥了至关重要的作用。

Application of computer technologies in construction of green cityin western china

This paper summarizes computer technologies in green city constructionin western China, which includes risk assessment and early warning of geological disasters, ecological city planning and infrastructure construction, and green building structure system. In the risk assessment and early warning of geological disasters, GIS technology is applied together with remote sensing technology to acquire basic information of large-scale geological hazards, which is in favor of monitoring and early invention of hazards. In the ecological city planning and infrastructure construction,the earthwork analysis and land use evaluation with GIS technology, the regional traffic simulation with Transcad technology, the wind environment simulation with CFD technology and the sunshine simulation with Zhongzhi software are gradually given attention and further applied. In the green building structure system, finite element numerical method and parallel computing are playing important roles in seismic analysis of civil engineering structural systems.
