| 摘 要： | 针对传统以皮尺为主要工具的岩体裂隙迹长测量方法精度及效率较低、尤其是遇有危险场地不能遥测等缺点,研究应用数字近景摄影测量的方法获取岩体裂隙迹长信息,以普通非量测数码相机为主要工具,以JX-4A数字摄影测量工作站为依托进行信息处理,可以快速获取隧道施工掌子面裂隙迹线图。经实验比较分析,数字近景摄影测量方法获取岩体裂隙信息在精度和效率方面都优于传统方法。

| Abstract: | Traditional method taking tape as main tool to measure trace length of rock mass crevice has lower accuracy and efliciency,especially,it can not realize in dangerous field.A new method applying digital close-range photogrammetry to achieve trace length information of rock mass crevice is reported.This method takes common digital camera as a main tool to collect information of rock mass crevice and depends on digital photogrammetry workstation of JX-4A to process information.In this way the tunnel building face crevice trace chart can be gained speedily.After the experimental evaluation,this method is thought to be superior to traditional one. |
