 note = {Shield construction works are the most popular method employed at the Taiwan Mass Rapid Transit project and underground sewage projects. Joining of the shaft and the tunnel is generally high-risk work because of potential dangers, such as ground collapse and tunnel breaks. Accordingly, we measured the strength of geological improvement at the shield shaft and its P-wave velocities using a boring core and test piece. The test results show that the relationship between the unconfined compressive strength and P-wave velocities is very close. P-wave velocities can be used to estimate density. P-wave velocities will probably become a quality control test yardstick in future.},
