Autor: Yunhe Ao, Chuang Sun, Baoxin Jia, Jianjun Zhang

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-19 (2022)

Abstract In order to analyze the influence of meso-structure and meso-parameters on deep granite characteristics, a construction method of variable radius proportional clump model was proposed with particle flow method. The clump particle flow struct

Publikováno v: PLoS ONE, Vol 16, Iss 8, p e0256243 (2021)

Proper mechanical model selection is critical in tunnel support design and stability analysis, especially to reflect the creep and strain-softening behavior of soft rock. We present a coupled nonlinear Burgers strain-softening (NBSS) model and numeri

The Research on Strain-Softening Characteristics and Local Fracture Law of Deep Granite Roadway

Autor: Chuang Sun, Yunhe Ao, Laigui Wang

Publikováno v: Complexity, Vol 2020 (2020)

The complex mechanical properties of deep surrounding rocks during excavation and unloading have always been a concern in engineering communities. Based on deep roadway engineering, the mechanical properties of granite strain-softening were investiga
