Overview

Randomized trial investigates mechanical properties and failure mechanisms in rock masses with various flaws, highlighting stress impacts.

Key Points

This research aims to understand how different stress paths and flaw types affect the failure mechanisms and mechanical properties of rock masses.
Employed meso-damage numerical simulation to analyze heterogenous rock masses.
Investigated various flaw types under different stress conditions.
Performed uniaxial and triaxial compression tests to assess mechanical properties.
Flaw propagation involves extension and coalescence of wing and anti-wing flaws.
Tensile coalescence failure occurs under certain stress conditions; changing the direction alters failure types.
Confining pressure enhances rock mass peak strength, particularly orienting internal stresses towards flaw planes.
