minimum stress is the vertical stress.Hence despite the orientation of the fracture on the borehole wall there is the possibility that the fracture will end in a near horizontal orientation and the interpreted results will reflect the ... C.D,Martin,R Christiansson - Isrm-sponsored International...
When soil in region III is in the limited state, longitudinal stressσzis the minimum principal stressσ3and horizontal stressσxis the maximum main stressσ1. So we can get: pP=qcot2π4−φ2+2ccotπ4−φ2 (8) wherecis cohesion. ...
