【摘要】：为促进盾构隧道工程生命周期各阶段之间的信息共享,建立统一的盾构隧道信息管理标准,对IFC标准进行了盾构隧道结构相关的扩展,提出了基于IFC标准的盾构隧道数据模型。通过对现有的IFC标准中关于工程对象描述方法的分析,确定了扩展的方向和范围。选取盾构隧道管片结构为研究对象,结合盾构隧道结构的特点,在现有IFC标准关于空间结构定义的基础上,建立隧道整体、隧道分部、衬砌空间和管片环等逐级细化的空间结构表达;在现有IFC标准关于物理元素描述的基础上,重点建立管片块的物理元素表达;为空间和物理结构建立包含其常见属性的属性集合并通过关系实体将建立的各类描述实体、属性集合之间建立关联关系。通过上述针对盾构隧道的IFC扩展,实现了基于IFC的盾构隧道信息模型的数据表达,为建立盾构隧道信息模型提供了数据组织结构和存储标准,有助于实现岩土工程信息化。
[Abstract]:In order to promote the information sharing between various stages of the life cycle of the shield tunnel project, a unified information management standard for shield tunnel is set up, the IFC standard is extended to the shield tunnel structure, and the shield tunnel data model based on the IFC standard is put forward. The analysis of the existing IFC standard on the engineering object description method is determined. The section structure of shield tunnel is selected as the research object. On the basis of the existing IFC standard on the definition of space structure, the spatial structure of tunnel, tunnel, lining space and tube ring is expressed on the basis of the definition of the space structure, and the physical elements are described in the existing IFC standard. On the basis of this, we focus on the establishment of the physical element expression of the block block; establish the attribute set containing its common attributes for the space and the physical structure and establish the relation between the various description entities and the attributes set through the relational entity. Through the IFC expansion of the shield tunnel, the information model of the shield tunnel based on the IFC is realized. The data expression provides data organization structure and storage standard for the establishment of shield tunnel information model, and helps to realize geotechnical engineering informatization.
