| 摘 要： | 针对上海地区预制管片堆场堆放层数不确定、堆场布局混乱、管片定位查找困难等问题,将有限元法(FEM)和建筑信息模型(BIM)技术相结合,通过对管片堆放层数仿真分析与管片定位研究,以期找到解决这些问题的方法。为此,先采用Abaqus有限元软件对预制管片堆场进行数值模拟以确定预制管片堆场每个堆位的管片堆放层数,再通过Revit、Navisworks等BIM软件对预制管片堆场进行虚拟布局。在此基础上提出一种基于BIM的混堆模式预制管片堆场定位新方法,该方法以BIM模型为核心,通过与二维码物联网技术和龙门吊智能化控制系统相结合来建立数据的转换与融合,从而实现在BIM终端三维可视化界面下对堆场中的预制管片进行精确定位查找与龙门吊最优路线运输作业。

| Abstract: | The precast segment storage yards in Shanghai have many disadvantages, such as uncertain stacking layers of segment, disordered layout and difficult segment positioning. As a result, finite element method (FEM) and building information model (BIM) technology are adopted. Analysis and study are made on simulation of segment stacking layer number and positioning of segment. The precast segment storage yard is numerically simulated by finite element software Abaqus so as to determine the number of segment stacking layers of every stack. And then the precast segment storage yard is simulated by BIM softwares Revit and Navisworks. Finally, a new segment positioning method based on BIM mixed stacking mode is presented. The above mentioned method is cored on BIM and uses technology of two dimensional code internet of things and intellectualized control of gantry crane. In return, accurate positioning of precast segment and the optimal route of transportation and operation of gantry crane showed on 3D visualization interface of BIM terminal can be realized. |
