| Abstract |
This research collected work drilling report of TBM method site developed by WRITH company to TBM equipment company in Germany and analyzed work operating productivity. Based Oil the data analyzed TBM operating productivity, This research derived and presented excavation speed (m/day) by TBM diameter (3.0m, 3.5m, 3.8m) and rock. Also, based on the excavation speed (m/day) by TBM diameter, This research estimated a day direct construction cost and total direct construction costs by applying a direct construction cost which spent on per 1m. When we perform a similar geological construction in the future, excavation speed and direct construction cost which were derived by TBM diameter and rock is thinking the effective utilization data to estimate construction cost and plan schedule management before the start of construction. |
