A New Evaluation Method for the Uniaxial Compressive ...

Uniaxial compressive strength (UCS) is a very important fundamental mechanical parameter for TBM construction. In this work, a predictive model of UCS was proposed according to the TBM parameters including torque, penetration, cutter number, and cutter diameter. The parameter of the new proposed model was established by fourteen existed TBM tunnels’ construction data.

Definition of Concrete MPa | Hunker

The English unit equivalent to MPa is pounds per square inch (psi). While the U.S., U.K. and a few other countries use psi, the majority of countries rely on MPa. Many manufacturers, builders and suppliers provide product data showing both MPa and psi ratings for concrete materials. To convert psi to MPa, multiply the psi value by 0.0068915.
