摘要

伴随着我国经济的发展，人口的增长和城镇化率的提高，城市交通也日渐紧张起来，地铁已经成为减轻城市交通压力的主要出路。目前地铁建设进入到了一个高峰期，隧道质量问题也接踵而至。盾构法是指采用管片作为衬砌结构，将成环管片沿着隧道设计轴线长度方向刚性安装铺就组成隧道的一种施工方法。盾构法由于具有施工速度快、对周围环境影响小、安全性高等自身优势，已在隧道施工方法种占据主导地位。在盾构法隧道中，管片全生命周期质量直接决定整个隧道工程的质量。管片检测技术是指在隧道施工中，对管片、管环及成型隧道进行质量管理的一种重要技术手段，然而采用人工工作的方法，存在信息处理慢、信息不共享等问题，如何借助信息技术，实现检测信息的集成化管理，已经成为一种需求和趋势。

本文首先通过对管片全寿命周期质量管理要点分解，分析了管片各个阶段的检测信息，重点介绍了设计阶段的轴线坐标计算方法、楔形量确定等，为隧道轴线和管片在BIM中的建模打下基础。

然后，基于IFC标准模型体系、扩展方式和图形表达方法，对管片检测信息进行了表达和扩展，建立了基于IFC标准的管片检测信息模型。该模型采用中性数据机制对管片检测信息表达，实现了BIM与检测信息的集成。集成化的检测信息作为信息共享平台的数据库，支撑共享平台上层的管理系统，使得管片检测信息能够在全寿命周期各阶段、各参建方之间自动交换和共享，保证隧道质量。

最后，以某城市地铁三阳路隧道工程为例，构建了隧道管片检测信息共享平台。该平台实现了不同参建方与管片检测信息数据库之间的信息交换，从而达到了检测信息的共享，提高了检测工作的效率和质量。

Abstract

The pressure on urban traffic has been increased, along with the development of economy and the increase of population. In order to alleviate traffic pressure, subway has already been become an important transport medium in people’s daily life. Tunnel construction has entered a peak period, accompanying with the problems of tunnel quality. Nowadays, shield method has occupied dominant position in tunnel construction methods. And shield tunnel is paved with loops composed of segments along the tunnel axis direction, using segment linings as permanent supporting structure. That is to say, the quality of segments and segments rings determine the quality of the whole product. Segment detection is an important technical method to control the quality of segments and segments rings in the construction process. Detection information process slowly and are not sharing, because artificial methods are still used for Segment detection . Integrated management of detection information has gradually become a kind of demand and trends by using information technology.

By analyzing the keys of segments’ quality management, the segment detection information at various stages of the whole segment construction was collected, and the tunnel design axis coordinate calculation, wedge quantity optimization, etc. were demonstrated, which laid the foundation for tunnel axis and segments modeling in BIM. Then, segment detection information was expressed and extended based on the IFC standard model system. And detection information modeling was established based on IFC standards, The model adopts the mechanism of neutral data segment detection information expression, which can integrate the BIM and segment detection information and as the database of segment detection information sharing platform, it, for exchanging and sharing information and guarantee the quality of the tunnel.

Finally, taking Sanyang Road tunnel as an example, tunnel segment detection information sharing platform was built. On the platform, information exchanging between participants and information database was realized, so information sharing among all participants was achieved, and the efficiency and quality of the detection work could be improved.
