数码摄影(CCD)技术在隧道施工地质调查中的应用

Application of Digital Photography (CCD) in Geological Investigations during Tunnel Construction

常规隧道施工地质编录现状急需一个高效快速手段来支撑。CCD数码地质编录系统首次引入我国铁路客运专线的施工地质调查中。介绍了该系统的原理与方法,并进行了施工地质编录与围岩级别划分的工程实践,指出了存在的问题,对该系统在隧道施工地质调查与工程应用的前景提出了看法。

An efficient geological logging method is urgently needed in the tunnel construction. CCD digital geological logging system is introduced into the geological investigations in the construction of the tunnels on the passenger-dedicated railways in China. In the paper, the principle and method of CCD digital geological logging system are presented and engineering practice of geological logging and rock mass grading is conducted. Furthermore, the problems of CCD digital geological logging system are pointed out and the prospect of the application of CCD digital geological logging system in the geological investigation during tunnel construction is provided.
