Abstract

Based on the background of significance of railway construction, introduces the design of bridge construction organization, from project summary to the organization and time limit for a project plan, and then to the construction preparation, construction process, construction process control, and finally to the construction safety and civilized construction, describes the overall system a bridge from the construction preparation stage to eventually become a real project entire process. Article concise, easy to understand, the overall system, let a person see the form immediately after the very clear thinking, to the whole construction procedures have a very clear understanding. Article focuses on the construction technology, construction methods of the project and the control of the construction process. For our civil engineering professional, quality control, technical level, time limit control is particularly important. The article take large space to introduce construction technology, construction method and construction process control, it is tightly organic combination of the three aspects. This article from the first step in the bridge construction of open caisson pile construction to bridge construction of ancillary facilities are given to the detailed explanation, deepened our understanding of bridge construction. For bridge construction control project in the process of introduction, and emphatically introduces the quality assurance measures, this make us more to understanding the concept of enterprise of engineering quality for this. Article the last few chapters also introduced the construction safety, conservation and civilized construction, which in turn reflects the image of an enterprise, and strictly follow the \prevention first, comprehensive management\synchronous implementation of the construction of production and

environmental protection, synchronous construction, principles of synchronous development.

Keywords：Construction process; Process control; Civilization construction

石家庄铁道大学毕业设计

第1章 绪论

施工组织设计属于技术文件，于设计招投标、施工阶段时期进行提交，为项目负责人统筹生产活动，规范项目治理，协调进程与优化配置资源的根据。

施工组织设计同时也是工地领导进行劳动力分配和机械配置的依据。 施工组织设计是项目全体员工进行施工生产等活动的行动纲领 施工组织设计是编制施工预算定额的主要依据。

总之，施工组织设计对于能否优质、高效、按时，按质的完成桥梁项目施工任务有重要作用。

所以施工组织设计是工程项目的核心所在，编制一套完整清晰的施工组织计划是快速高效安全的完成施工的必要条件。
