【摘要】：作为建筑全生命周期中持续时间较长、对工程质量影响最为直接的施工阶段，存在诸如技术水平和管理理念落后、资源浪费现象严重、施工信息表达及传递模糊等问题。建筑信息模型（Building Information Modeling，简称BIM），通过参数化模型整合工程项目的各类相关信息，并在全生命周期过程中进行共享和传递，其可视化、协调性、模拟性、优化性的特点为其在施工中的应用奠定理论基础。本文在总结已有的BIM技术在施工阶段应用价值的基础上，主要作以下研究：（1）提出“基于BIM的实时模型”的概念，并介绍实时模型的创建方法，阐述现阶段BIM技术在施工阶段的应用思路及实现方法。（2）以实际工程案例为背景，从建筑施工现状和实际需求出发，依次创建满足不同情境需求的实时模型，展开在以下三方面的应用探讨： ①发挥BIM的参数化优势，实现混凝土灌注桩由三维模型到钢筋下料的直接提取。承载真实钢筋信息的混凝土灌注桩是该应用情境下的实时模型。基于自建钢筋族的通用性，可录入“实时族库”，为以后不同项目的混凝土灌注桩所用。 ②把施工模型精细化，形成顺应进度管理应用需求的实时模型，探讨其在4D模拟建造以及施工方案对比方面的价值。 ③充分利用BIM的设计效果可视化特点，补充完善视图及模型，，使该实时模型能够准确指导施工，尤其为复杂节点的施工指导所用。
[Abstract]:As the construction stage, which has a long life cycle and has the most direct impact on the quality of the project, such as the backward level of technology and management concept, the waste of resources is serious. Building Information Modeling (BIMM). Through the parameterized model to integrate all kinds of relevant information of the project, and share and transfer in the whole life cycle process, its visualization, coordination, simulation. The characteristics of optimality lay a theoretical foundation for its application in construction. On the basis of summarizing the application value of the existing BIM technology in the construction stage, this paper mainly makes the following research: 1) the concept of "real time model based on BIM" is put forward, and the method of establishing real time model is introduced, and the application and realization of BIM technology in construction stage are expounded. 2) based on the actual engineering case, starting from the actual construction situation and the actual demand, the real-time model to meet the needs of different situations is established in turn, and the application in the following three aspects is discussed. 1 give play to the parameterized advantage of BIM. The concrete cast-in-place pile can be directly extracted from the three-dimensional model to the steel bar material. The concrete cast-in-place pile bearing the information of the real steel bar is the real-time model in the application situation. Based on the generality of self-built reinforcing bar family. Can be input into the "real-time family library", for the future of different projects of concrete pile. (2) the construction model is refined to form a real-time model to meet the requirements of schedule management, and its value in 4D simulation construction and construction scheme comparison is discussed. (3) make full use of the visual features of design effect of BIM, complement and perfect the view and model, make the real-time model can guide construction accurately, especially for the construction guidance of complex nodes.
