[STT13-01] Numerical interpretation of anchoring mechanism by using Bonded Particles Model

Yoshitada MITO1, *Kohei NISHIDA1 (1.Fac. of Engineering, Kyoto University)

Keywords:ground anchor, distinct element model, crack initiation and propagation

In order to clarify the anchoring mechanism of ground anchor and develop the effective design method, it is convinient to build the numerical model that can well reproduce the mechanical behavior and represent the fracturing process around the anchor part under various specific conditions. The mechanical behaviors of ground anchor are simulated by distinct element methoed using bonded particle model. As the result of the simulations, the typical mechanical behaviors and the well-known empirical law of ground anchor can be well reproduced.
