【摘要】 地铁工程涉及专业广、建设周期长、内容复杂,且属于线形工程,采用CPM方法编制进度计划,会导致进度计划非常的复杂、难以直观反映任务的地理位置及工作面搭接关系和施工过程中的空间冲突问题。提出一种基于线形图的地铁工程进度管理方法,形象地显示地铁工程的每一个任务的地理位置和耗费的时间,以及同一工作面上不同任务的位置搭接关系。并通过构建基于线形图的进度冲突识别算法,实时检测当前进度计划可能存在的空间冲突问题。在此基础上,通过数据库将进度计划与3D/CAD模型建立关联关系,构建4D可视化进度管理系统,直观地反映施工过程中的空间冲突问题。本系统在某地铁工程中成功应用,及时发现了施工计划中的空间冲突问题,实现了对项目实时、精准的控制,提升了地铁工程进度管理的水平,提高了投资效益。更多还原

【Abstract】 Metro project involves lots of expertise,long construction period,and complicated construction environment,and it is categorized as linear projects.CPM method for metro project planning not only causes the scheme to be significantly complex to reflect the mission’s location and interface overlapping relationship,but also is unable to solve the space conflicts in construction.Therefore,it is necessary to propose a subway schedule management method which is based on linear schedule and simple express schedule of linear project.Such method should be able to effectively reflect the location of tasks and relationship of overlapping joint between the various tasks.Building 4D visualization schedule management system based on the linear planning method can solve the space conflicts in construction effectively,achieve real-time and precise control,enhance the schedule management of subway constructions,and improve the investment efficiency.更多还原
