Paper presented at the ISRM International Symposium, August 30–September 2, 1989
Paper Number: ISRM-IS-1989-113
... ABSTRACT: The mechanical behaviour of high porosity weak rocks is discussed with reference to standard drained triaxial and Ko tests on high porosity chalk. Similarities are drawn with other high porosity cemented materials. During one-dimensional compaction of weak rocks, large volume...
