Interaction of cutting disc with heterogeneous ground
- In this contribution, the peridynamic theory [1] is utilized to analyze the interaction of cutting disc of a Tunnel Boring Machine (TBM) with mixed (heterogeneous) ground conditions. Peridynamic formulations, in contrast to classical continuum theory, do not contain spatial derivatives [1,2], which makes it a preferable tool for modeling phenomena involving discontinuities, such as complex fracture and fragmentation processes [3]. The model was initially used to simulate a full-scale Linear Cutting Machine (LCM) test for various penetration levels [4]. The cutting forces obtained were in agreement with the experiment [5]. Excavation process in mixed ground conditions is analyzed using simulations in which a cutting disc moves from a soft ground (soil, weathered rock or soft rock) region into a hard rock region. There is a sudden increase in the force on the cutting disc as it moves from a soft to hard ground, this abnormal peak in force is further investigated with respect to various tool penetrations.
