Abstract: |
Characterizing performance of tunnel boring machines (TBM) is important for numerous contractual and technical reasons. A common tool to determine machine performance in the field is the penetration test. The purpose of the penetration test is to operate the TBM for a defined period of time under normalized conditions that allow for interpretation and comparison between tests. The result of a penetration test is a thrust-penetration curve that reflects the excavatability of the rock mass. Prediction models use thrust-penetration curves to calculate the expected performance of a TBM in specific ground conditions. |
