Abstract

In this paper failure process of rock with a partially-spanning joint is presented by numerical simulation based on RFPA2D. numerical simulation shown that mechanical behavior of jointed rock mass is governed by both the mechanical characteristics of the discontinuities and those of the intact rock, jointed rock mass behavior tends to be dominated by the mechanical properties of the weaker join planes that occur within the rock mass, rather than the mechanical properties of the intact rock,. the failure of rock with a partially-spanning joint begin first in joint, with the increase of the vertical load, joint is expanded along the joint plane within the rock mass, the damage area expands unceasingly, Numerical simulation shown that failure model of rock with a partially-spanning join, Peak load, compressive strength are near to the real physical experimental results containing partially-spanning joint.
