【摘要】：桥梁钢沉井是大型桥梁的主要支撑结构组成部分,是桥梁建造的基础。对于大型及特大型桥梁钢沉井如何实现完整性建造和安装的水平不仅反映了钢结构建造的先进水平,也代表着桥梁建造的水平。沪通铁路长江大桥是苏北连接长三角的重要交通枢纽,其主桥墩钢沉井的建成将是目前世界体积最大、最高的桥梁钢沉井结构。本文依据项目管理理论对RS公司承担建造的沪通铁路长江大桥主桥墩钢沉井进行进度管理的组织、计划、控制等过程的研究。本论文分析了此次研究的背景和意义,分析项目的特点及RS公司、业主方、总承包方为适应项目建造采取的项目组组织结构。在项目组织结构及项目特点的基础上对项目进行了WBS划分,分析了各项目活动之间的逻辑关系以及估算各项目活动的时间。进而确定了项目的关键路径和进度计划,并进一步论述了如何利用调整活动逻辑关系对进度计划进行了优化,克服了工期紧张的问题。接着,本论文分析了为确保项目进度计划在可控范围内执行,分析了可以采取的一系列项目进度计划控制手段和方法。指出了该项目由于建造方自身问题而存在的风险和控制方法。最后总结了此次项目进度管理的经验,分析了项目执行过程中存在的问题,并通过运用赶工、增加资源投入、调整逻辑关系、合理建立搭接关系等应对措施,达到了最终满足项目工期的要求。
[Abstract]:Bridge steel caisson is the main supporting structure of large bridge. It is the foundation of bridge construction. The level of how to achieve integrity construction and installation of steel caisson for large and super large bridges not only reflects the advanced level of steel structure construction. It also represents the level of bridge construction. The Yangtze River Bridge is an important transportation hub connecting the Yangtze River Delta in the north of Jiangsu Province. The completion of the steel caisson on the main pier of the bridge will be the largest volume in the world at present. The highest bridge steel caisson structure. According to the project management theory, this paper carries on the schedule management organization and the plan to the main pier steel caisson of the Shanghai Stock Connect Railway Yangtze River Bridge undertaken by RS Company. This paper analyzes the background and significance of this study, the characteristics of the project and RS company, owner. The project group organization structure adopted by the general contractor to adapt to the construction of the project. On the basis of the project organization structure and the characteristics of the project, the WBS division of the project is carried out. The logical relationship between each project activity is analyzed and the time of each project activity is estimated. Then the key path and schedule of the project are determined. Furthermore, it discusses how to use the logic relation of adjusting activities to optimize the schedule, which overcomes the shortage of time limit. Then, this paper analyzes how to ensure that the project schedule can be carried out within a controllable scope. This paper analyzes a series of project schedule control methods that can be adopted, points out the risk and control methods of the project due to its own problems, and finally summarizes the experience of the project schedule management. This paper analyzes the problems existing in the implementation of the project, and through applying the measures of rush work, increasing the resource input, adjusting the logical relationship and establishing the reasonable overlap relationship, achieves the final requirement of meeting the project duration.
