DOI: 10.1007/s10706-017-0278-9
Abstract: As soft rocks are likely to soften, slime and swell while contacting water, the existence of soft rocks is harmful for stability of surrounding rocks and supporting structures of tunnels. Through uniaxial and triaxial tests… read more here.

DOI: 10.1016/j.compgeo.2017.07.003
Abstract: Abstract The behavior of soft rock depends on the contact area between mineral particles and the tensile strength of the interparticle cementation, which are usually referred to as structures. We investigated the effects of structural… read more here.

DOI: 10.1016/j.compgeo.2018.12.029
Abstract: Abstract This study investigates the strength and stress-strain relationship of jointed soft rocks using undrained triaxial compression testing. A bounding surface plasticity model considering overconsolidation and structural decay is proposed for jointed soft rocks. Specifically,… read more here.

DOI: 10.1061/(asce)gm.1943-5622.0001774
Abstract: The creep of soft rocks induced by seepage-stress coupling is one of the critical factors that causes the failure of the rock. However, the actual failure mechanisms of soft rocks, particularly during the accelerated creep… read more here.
