About this document
Specific Energy of Excavation in TBMs by Reza Osgoui is a document available to read on EtoBox.
This document discusses the concept of specific energy of excavation (SEE) as it relates to tunnel boring machines (TBMs). The SEE is defined as the energy involved in excavation per volume of ground excavated. It can be used to characterize rock masses and detect changes in ground conditions in real-time. The SEE depends on the size of rock fragments produced and methods using explosives require the least energy. For TBMs, the SEE has two components - energy for thrusting the machine forward and energy for
