【摘要】：项目进度计划是工程项目管理的重点内容,科学合理地编制和运用项目进度计划是保证工程项目施工组织工作有序开展和整体经济效益目标顺利实现的关键环节。铁路作为我国国民经济的基础产业,目前正处于大规模的建设阶段,为了保证铁路建设工程施工的质量和效率,同时考虑施工过程中众多因素对施工进度的影响,编制更为贴近实际施工情况的施工变速率进度计划,对于铁路建设工程项目管理具有非常重要的意义。铁路建设工程作为典型的线性工程,当前采用的甘特图或网络计划方法并不能很好地适用于该类工程的进度计划编制并展现出工程的施工特点。本文在分析国内外工程进度计划编制研究现状的基础上,以适应铁路建设工程进度计划编制的线性计划方法为研究对象,依据影响施工进度因素变化的时空特性提出基于时间-空间的影响因素划分方法,通过与铁路建设工程时空网格的结合构成了施工变速率进度计划编制的理论基础。本文收集整理实际工程的进度数据,利用多元线性回归分析方法确定了施工活动的速率与影响因素之间的关系,进而构建了基于网格的施工速率回归模型,并通过对施工活动进出基本网格单元位置的探讨实现了基于LSM的中国铁路施工变速率进度计划编制模型的构建。最后,结合乌准铁路五彩湾至将军庙段路基工程的实际数据对模型的有效性进行了验证。
[Abstract]:Project schedule is an important part of project management. Drawing up and using the project schedule scientifically and reasonably is the key link to ensure the construction organization of the project to be carried out in an orderly manner and the goal of overall economic benefits to be realized smoothly. The railway is the basic industry of the national economy of our country. In order to ensure the quality and efficiency of railway construction, the influence of many factors on the construction progress is considered. It is of great significance for railway construction project management to draw up the construction variable rate schedule which is closer to the actual construction situation. As a typical linear project, railway construction project, The current Gantt chart or network planning method can not be used to draw up the progress plan of this kind of project and show the construction characteristics of the project. This paper analyzes the present situation of the domestic and foreign research on the preparation of the progress plan of the project. Taking the linear planning method for railway construction progress planning as the research object, according to the temporal and spatial characteristics of the factors influencing the construction schedule, the method of dividing the factors based on time and space is put forward. Through the combination of time and space grid of railway construction project, the theoretical basis of construction variable rate schedule is formed. This paper collects and arranges the progress data of the actual project, determines the relationship between the speed of the construction activity and the influencing factors by using the method of multiple linear regression analysis, and then constructs the construction rate regression model based on the grid. By discussing the location of the basic grid cells in and out of the construction activities, the establishment of the model of the Chinese railway construction schedule with variable rate based on LSM is realized. Finally, The validity of the model is verified by the actual data of roadbed engineering from Wucai Bay to Jiangmiao section of Wuqi Railway.
