Cost benefit ratio model and stage rolled method are chosen as the theoretical foundations of the program, and then benefit model is improved to accord with the actuality of urban traffic in China. Consequently, program flows, module functions and data structures are designed, and particularly an original data structure of road ...展开更多

Through using construction sustainability tools, methods and techniques, a greener design can be applied during various building phases. In this connection, it is argued that the analytical and integrated models applied by Building Information Modelling (BIM) may also facilitate this process to be performed more efficiently. BIM and construction sustainability are quite different initiatives, but both have received much attention in recent years in the architecture, engineering and construction (AEC) industry. A rigorous analysis of the interactions between them implies that a synergy exists which, if properly it is understood that can be helpful to reduce the environmental impacts of the AEC industry. A BIM-based design model can contribute to sustainability through its three main dimensions which are environmental, economic and social. In this paper, by reviewing the existing literature on BIM and construction sustainability and using a matrix to analyze construction sustainability dimensions and BIM functionalities a number of interactions have been discussed. It can be concluded that despite there are many improvements in implementation of BIM in environmental and economic aspects of sustainability, its potential impact on social dimension has not been explicitly explored hence further studies need to be undertaken in this area.展开更多
在水利工程的建设管理中,施工进度会不可避免地受到外界因素的影响,导致工程施工不能按照原有计划进行。针对于此提出了基于BIM+GIS的施工进度动态计划关联方法,以互联网技术为基础,结合数据库技术和可视化技术,实现工程量统计与施工进...在水利工程的建设管理中,施工进度会不可避免地受到外界因素的影响,导致工程施工不能按照原有计划进行。针对于此提出了基于BIM+GIS的施工进度动态计划关联方法,以互联网技术为基础,结合数据库技术和可视化技术,实现工程量统计与施工进度的动态模拟,通过Cesium 3D GIS平台建立了基于BIM+GIS的水利工程施工进度管理系统。此系统将GIS大场景与BIM深度结合,为水利工程项目参建方提供施工三维动态可视化环境,精细化控制水利工程的工程量统计与进度计划管理。目前该系统已经在某水闸工程中投入使用,应用效果良好。展开更多
