通过现场试验，将三维激光扫描技术与数码摄影地质编录进行应用对比，了解三维激光扫描技术在隧道掌子面及边墙地质信息提取的应用效果，根据现场实际需求情况，将两者优势进行集成，为开发新型隧道地质编录系统开拓思路。试验证明： 利用现有三维激光扫描软件系统，实现如地质产状等信息的自动提取还有一定距离，但经过后期软件开发，利用激光回波强度分析、点云数据处理等，三维激光扫描技术具有产状自动识别、岩层厚度计算、掌子面前方产状预测等潜在优势。现有数码摄影地质编录系统也无法进行编录要素自动提取，但现场边墙编录效果好于三维激光扫描技术。

3dimensional laser scanning technology and digital imaging geology catalog system are compared by means of site tests. The effect of the application of 3dimensional laser scanning technology in the acquisition of the geological information of the tunnel faces and sidewalls is obtained. The advantages of 3dimensional laser scanning technology and digital imaging geology catalog system are combined so as to develop new geology catalog system for tunneling. The test results show that the existing 3dimensional laser scanning software cannot acquire the information of geological occurrences automatically; However, the 3dimensional laser scanning technology has potential advantages in automatic occurrence identification, rock strata thickness calculation and prediction of occurrences ahead of the tunnel face when new software is developed in the future and laser attribute analysis technology and point cloud data processing technology are used; The existing digital imaging geology catalog system cannot acquire the geological information automatically, but it is better than 3dimensional laser scanning technology when it is used to acquire the geological information of side walls. 
