Use of indentation tests to study the influence of confining stress on rock fragmentation by a TBM cutter

Jian Zhao, Lijun Yin, Hongsu Ma

This paper explores the influence of the confining stress on rock fragmentation under the cutter of tunnel boring machine (TBM) by indentation test. Acoustic emission (AE) system was employed for real-time monitoring the rock fragmentation process during t ...

Numerical study of the effect of confining stress on rock fragmentation by TBM cutters

Lijun Yin, Hongsu Ma

This paper investigates the effect of confining stress on rock fragmentation under TBM cutters by numerical simulation. Firstly, based on the characteristics of the force-penetration curve, the confining stress conditions for TBM tunneling are divided into ...
