Abstract

Mechanical excavation is widely used in construction of tunnels for civil and mining applications. Tunnel boring machines are popular since they excavate the rock in an almost continuous process. In TBM tunneling, the main issue is predicting rate of penetration, since that determines how much time is needed to complete the project. Tunnel boring machine performance in both hard and soft rocks is complex process that depends mainly upon geological conditions and machine specifications. Geotechnical parameters such as rock fractures, faults, strength and texture of rock, and tunnel boring machine parameters such as both thrust and torque requirement, control the rate of penetration.
The objective of this paper is to evaluate and identify the major geotechnical and machine parameters influencing the TBM performance. Also, some laboratory tests are recommended to evaluate physical properties of rocks in order to facilitate prediction of TBM performance.
