【摘要】：本文结合GIS技术进行了灌注桩可视化施工管理系统研究,将灌注桩的施工信息在数据库中进行更新、管理及显示。确定施工信息在数据库中的两种不同存储方式：完全数字化的存储方式与整体文件以字节流形式存储；提出了企业—服务器、工程项目—数据库、项目施工信息—数据表的数据存储结构；将GIS可视化技术用于灌注桩施工信息可视化,以矢量数据来绘制桩基的点状分布图,根据施工状态不同区别显示；对地理信息系统中主要的三维空间模型如面模型、体模型等进行了探讨与对比,选择基于多层DEM表示的面模型来表达地基土层信息,地表与各土层的DEM由含高程信息的离散点构建TIN得到；在C#下使用ArcEngine根据可视化功能要求,实现区别显示不同施工状态下的二维桩位分布和地层的三维分层显示功能。结合灌注桩施工管理的实际需求以及基础工程公司对系统的使用要求,对系统应该具有的功能要求和系统架构以及主界面下的操作流程进行研究和选择,灌注桩可视化信息管理系统的功能包括：桩基础信息管理包括施工现场记录、质量信息管理及数据批量导入功能；灌注桩施工项目数据库管理功能；报表打印功能；施工资料整体存取功能；辅助功能等。基于GIS的灌注桩可视化信息管理系统为灌注桩的施工提供先进的管理方法,作为管理者分析、决策的依据,具有重要的实用意义。
[Abstract]:In this paper, the visual construction management system of cast-in-place pile is studied in combination with GIS technology, and the construction information of cast-in-place pile is updated in the database. Management and display. Determine two different storage methods of construction information in the database: completely digitized storage mode and integral file storage in the form of byte stream, proposed enterprise-server, engineering project-database, The GIS visualization technology is used to visualize the construction information of the cast-in-place pile, and the vector data is used to draw the point distribution map of the pile foundation, which is displayed according to the different construction state. In this paper, the main 3D spatial models such as surface model and volume model in GIS are discussed and compared. The surface model based on multi-layer DEM is selected to express the ground soil information. The DEM of surface and soil layers is obtained by constructing TIN from discrete points with elevation information, and under C #, using ArcEngine according to the visual function requirements, the two-dimensional pile distribution and the three-dimensional stratification display of strata under different construction conditions can be distinguished. According to the actual demand of construction management of cast-in-place pile and the requirement of foundation engineering company to use the system, this paper studies and selects the functional requirements and system architecture of the system, as well as the operation flow under the main interface. The functions of the visual information management system of cast-in-place pile include: the information management of pile foundation includes construction site record, quality information management and data batch import, database management function of cast-in-place pile construction project, report form printing function, and so on. The visual information management system of cast-in-place pile based on GIS provides advanced management method for the construction of cast-in-place pile, which is the basis of management analysis and decision-making, which has important practical significance.
