  • The process of constructing the DB in the current geotechnical information DB system needs a lot of human and time resource consumption. In addition, it causes accuracy problems frequently because the current input method is a person viewing the PDF and directly inputting the results. Therefore, this study proposes building an automatic digital DB using AI (artificial intelligence) of boring logs. In order to automatically construct DB for various boring log formats without exception, the boring log forms were classified using the deep learning model ResNet 34 for a total of 6 boring log forms. As a result, the overall accuracy was 99.7, and the ROC_AUC score was 1.0, which separated the boring log forms with very high performance. After that, the text in the PDF is automatically read using the robotic processing automation technique fine-tuned for each form. Furthermore, the general information, strata information, and standard penetration test information were extracted, separated, and saved in the same format provided by the geotechnical information DB system. Finally, the information in the boring log was automatically converted into a DB at a speed of 140 pages per second.

  • 향수직굴착용장비로는 승갱굴착기(Raise Boring Machine)과 레이스크라임버(Raise Climber)로 나눌 수 있다. 이장에서는 수직굴착용장비가 다수 있으나 일부장비를 간략하게 소개하며, 추후 공법에 대한 설명할 기회가 주어진다면 좀더 다양한 장비 및 공법에 대해 자세히 기술하도록 하겠다.
