【摘要】：随着我国高速铁路技术的日益成熟,高速铁路建设进入了大规模、高科技和高标准的快速发展时代,项目进度管理已成为高速铁路工程项目管理的核心。为了满足国家高速铁路快速发展的需要,运用先进的铁路建设项目管理方法,并结合国内外先进的高速铁路建设过程的管理经验,实现项目进度管理科学化、信息化是目前高速铁路项目管理研究的热点之一。项目进度管理作为项目管理的重要环节,通过对项目进度管理概念与特点加以分析与总结,结合高速铁路立交特大桥项目进度管理特点,进行高速铁路立交特大桥项目进度管理研究。高速铁路立交特大桥项目进度管理研究主要包含三个方面:项目进度计划编制、项目进度计划预警和进度管理控制评价。基于WBS工作结构分解和关键路径法原理编制项目进度计划,并结合高原戈壁地区高速铁路特大桥——土墩2#立交特大桥进行分解,并确定了各项工作的活动顺序,估算了各分项活动的时间,绘制了项目进度计划网络图,编制了某高速铁路立交特大桥的项目进度计划,并结合对项目进度管理的研究,从人为因素和客观因素两方面分析了项目进度的影响因素,并结合高原戈壁地区高速铁路特大桥的特点,提出了土墩2#立交特大桥建设进度管理保证措施。结合高铁项目进度管理特点,基于数值分析法进行项目进度延误预警分析,土墩2#立交特大桥进行了工程预警分析结果表明:根据预警分析提供的信息信号,工程项目在6~7月份月份进度产生较大的延误;在8月以后项目进度的延误程度呈现下降的趋势;基于挣值法进行了高铁立交特大桥项目进度管理控制评价,并选取土墩2#立交特大桥项目进展了5个月的节点进行分析,分析结果表明:项目进展5个月后总体进度落后不严重。为了节约成本,提出了压缩关键路径工期和保证材料供应等项目进度偏差纠正措施,取得了较好效果。通过对高原戈壁地区高速铁路土墩2#立交特大桥进行项目进度管理,分析了影响了高速铁路土墩2#立交特大桥进度管理的因素,为后续相关类似工程提供参考。
[Abstract]:With the rapid development of high-speed railway technology in China, the construction of high-speed railway has entered a rapid development era of large-scale, high-tech and high standards. Project schedule management has become the core of high-speed railway project management. In order to meet the needs of the rapid development of the national high-speed railway, the scientific management of the project schedule is realized by using the advanced railway construction project management method and combining the management experience of the advanced high-speed railway construction process at home and abroad. Informatization is one of the hotspots in the research of high-speed railway project management. Project schedule management is an important part of project management. By analyzing and summarizing the concept and characteristics of project schedule management, the paper combines the characteristics of project schedule management of high-speed railway interchange super bridge project. Carry on the project schedule management research of the high-speed railway interchange super bridge. The research on project schedule management of high-speed railway interchange super bridge mainly includes three aspects: project schedule preparation, project schedule warning and schedule management control evaluation. Based on the work structure decomposition of WBS and the principle of critical path method, the project schedule is worked out, and combined with the super bridge of high speed railway in Gobi area of plateau, the earth mound interchange bridge is decomposed, and the order of activities of each work is determined. The time of each item is estimated, the network diagram of project schedule is drawn up, the project schedule of a super bridge of high speed railway interchange is worked out, and the project schedule management is studied. This paper analyzes the influencing factors of the project schedule from two aspects of human factors and objective factors, and puts forward some measures to guarantee the progress of construction of the overpass bridge in the highland Gobi area, combining with the characteristics of the high-speed railway bridge in the highland Gobi area. According to the characteristics of high speed railway project schedule management, the project schedule delay warning analysis based on numerical analysis method is carried out. The results show that according to the information signal provided by early warning analysis, the earth mound 2# interchange bridge is analyzed by engineering early warning analysis. The progress of the project was delayed in June and July. After August, the degree of delay in the project showed a downward trend. Based on the earned value method, the management control evaluation of the overpass bridge project was carried out. At the same time, the node which has been progressing for 5 months is selected and analyzed. The results show that the overall progress of the project is not serious after 5 months' progress. In order to save the cost, the corrective measures for the project schedule deviation, such as reducing the critical path duration and ensuring the supply of materials, are put forward, and good results are obtained. Through the project schedule management of high speed railway earth mound interchange bridge in Gobi area of plateau, this paper analyzes the factors that affect the schedule management of high speed railway earth mound 2# interchange super bridge, and provides a reference for related similar projects in the future.
