基于传统采用人工地质素描方法进行隧道掌子面分析的局限性,以贵阳市贵金线(金阳段)3号隧道为工程背景,对数码摄影图像处理技术及其在隧道地质判释中的应用进行了研究.研究过程中对掌子面图像数据采集技术、图像调整技术、局部图像拼接技术、掌子面岩层边界检测技术、图像特征提取技术以及掌子面地质状况预测方法等进行了详细论述.通过研究可提炼出岩层裂隙、节理以及地质构造等相关的数据,并进行量化评价,跟设计阶段围岩级别对比分析,实现围岩级别的修正;同时根据分析得到的掌子面信息,建立相邻掌子面上岩层间的对应关系,建立隧道已经开挖部分的三维地质结构模型,实现掌子面前方未开挖部分的地质结构信息预测,从而指导下一步的设计与施工.

Some limitations exist in the traditional artificial geological sketch method to analyze tunnel face, so image-processing technology of digital photography is adopted and its application in tunnel geological identification is studied by the case of tunnel 3 of line Guiyang to Jinyang in Guiyang. Face image data acquisition technology, image adjustment technology, local image matching technology, face rock boundary detecting technology, im-age feature extraction technology and geological condition prediction method are discussed in detail. Based on the study, data concerning rock cranny, joint and geologic structure can be obtained and quantitatively evaluated. Based on the comparison among surrounding rock levels at design stage, the levels can be revised. Meanwhile, according to the face information from the analysis, the corresponding relationships among the rocks on the adjacent face can be identified and the three dimensional geologic model of the tunnel part which is being excavated can be established so that the geologic struc-ture condition of the rest part can be predicted and future design and construction can be guided.
