【摘要】：现有的隧道爆破质量评价与控制大多依赖决策者的工程经验和主观认识,仅凭人为观测做定性分析,评价与控制成果一般表现为二维平面图,不能直观、可视化对隧道爆破质量进行表达。本文基于隧道数据采集模块、隧道数据前处理模块和隧道三维可视化模型构建模块等提出了隧道爆破质量三维可视化数字模型构建的方法,以成渝高铁某隧道为例,设计了隧道爆破质量三维可视化数字模型基础数据采集方案,建立了隧道爆破质量三维可视化数字模型,提出了隧道爆破质量综合评价的方法。研究结果表明,建立的三维可视化模型可再现隧道爆破超欠挖的真实结构特性,可实现对隧道爆破质量的综合评价,弥补目前隧道爆破质量评价与控制存在的不足。
[Abstract]:Most of the existing evaluation and control of tunnel blasting quality depend on the engineering experience and subjective understanding of the decision makers. The qualitative analysis is only based on artificial observation. The results of evaluation and control generally show two-dimensional plan, which can not be intuitionistic. Visualize the quality of tunnel blasting. Based on tunnel data acquisition module, tunnel data pre-processing module and tunnel 3D visualization model construction module, this paper puts forward a method of constructing 3D visual digital model of tunnel blasting quality, taking a tunnel of Chengdu-Chongqing high-speed railway as an example. The basic data acquisition scheme of 3D visualization digital model of tunnel blasting quality is designed, the 3D visual digital model of tunnel blasting quality is established, and the comprehensive evaluation method of tunnel blasting quality is put forward. The results show that the 3D visual model can reproduce the real structural characteristics of tunnel blasting overdigging and realize the comprehensive evaluation of tunnel blasting quality, and make up for the shortcomings of tunnel blasting quality evaluation and control.
