摘要: 高质量的隧道衬砌平整度不但对二衬防水施工有至关重要的影响,而且也是保证隧道线型、结构受力均匀及运营期防水系统持久有效的重要条件之一。三维激光扫描技术是近代广泛应用于隧道工程的一种集光、机、电及信息技术于一体的综合测量技术,得益于其现场海量点云的快速采集和分析能力,为隧道表面的平整度检测提供了一种全新的、可实施手段。本文将重点介绍在德庆隧道将高密度的三维激光扫描点云与隧道三维设计及计算机算法相结合的方法,实现高精度、无遗漏及可视化的隧道内表面平整度检测实践。

Abstract: High-quality tunnel lining evenness not only has a vital impact on the second lining waterproof construction,but also guarantees the tunnel's linearity, uniform structural force, and lasting and effective waterproofing system during operation.The 3D laser scanning system is a comprehensive measurement technology that integrates optical, mechanical, electrical and information technology widely used in tunnel engineering in modern times. It provides a new and implementable method for the evenness analysis of the tunnel surface thanking to its rapid on-site massive point cloud collection and analysis capabilities. This paper focuses on the practice of combining high-density 3D laser scanning point clouds with 3D tunnel design and computer algorithms in Deqing tunnel, which realizes high-precision,exhaustive and visual evenness analysis.

Key words: high-speed railway, tunnel, primary support, water proof, 3D laser scan, flatness
