Mechanical Behavior and Damage Fracture Mechanism of Deep Rocks

This book presents mainly experimental studies on the mechanical behavior and damage fracture mechanism of deep rocks including sandstone, marble, mudstone and granite, combining with several advanced technologies of X-ray micro-CT and AE monitoring.It has several unique features: 1) Investigates the influence of loading path on triaxial strength and deformation behavior of sandstone and marble; 2) Analyzes the effect of borehole size on triaxial strength and deformation behavior of hollow sandstone; 3) Explores the influence of high temperature on triaxial deformation and permeability behavior of sandstone and granite; 4) to reveal the damage fracture mechanism of deep rocks using spatial AE techniques and X-ray micro CT observations. This work will appeal to a wide readership from technicians in the field of geotechnical engineering and engineering geology to scholars carrying out research in the rock mechanics.

Offers systematic study on mechanical behavior and damage fracture mechanism of deep rocks Provides prolific figures of failed rock specimens by using X-ray micro CT observations Appeals to a wider group of audience from geotechnical engineering, engineering geology to rock mechanics
