- Abstract
In this paper,the strength properties of rock mass withrows of intermittent bidirectional cross joints by simulating models arediscussed.Work has been done on finding the failure mechanism of therock mass as well as the influence of joint direction and lateral pressureon tne strength of the rock mass.At the end of the paper,model testresults ahd FEM analyses are presented and strength criteria for thiskind of rock mass are proposed.
