摘要: 为解决传统铁路建设管理中进度数据采集标准化低、过程复杂和数据粒度粗等问题，提出了一种图形化施工进度数据处理方法.首先，采用面向对象的方法对工点进行工程分解，从施工图中自动提取出设计参数；然后，利用Web GIS技术设计开发图形化的施工进度数据采集系统，实现了进度数据的图形化填报与审核；最后，通过对进度数据进行统计分析，实现了进度数据驱动工点BIM模型进行三维形象进度展示，并生成进度统计与预警报表.以阳大铁路工程为例开展试验研究，研究结果表明：图形化的施工进度数据很好地满足了工程承包、施工、监理和业主等单位对高铁建设进行协同管理的需要，显著提高了工程施工进度管理水平和效率，节省进度统计分析工作量70%.Abstract: A method for processing data by graphical construction was proposed to solve the problems pertaining to acquisition of railway construction progress data, such as a low degree of automation and standardization, complicated procedure, and coarse data granularity. The object-oriented method was first used to deconstruct the engineering structure, and parameters were extracted automatically from design construction drawings; then, a graphical construction data acquisition system was designed and developed using Web GIS, graphical filling and auditing of progress data was realized, and the progress data drove the workbench BIM model to carry out the 3D display. Subsequently, a variety of progress report files could be generated automatically by statistical analysis of progress data. The Yangda Railway Project was employed as an example to verify the validity and feasibility of the proposed method. The results show that the graphical construction progress data satisfies the requirements of project contracting, construction, and supervision for owners and other units, for the coordinated management of high-speed railway construction; reduces statistical analysis work by 70%; and significantly improves the technical standard and efficiency of project construction schedule management.
