Determination of non-linear shear strength and volume changes on remolded granitic residual soil due to membrane penetration

Abstract Membrane penetration is the term used to describe displacement of rubber membrane into spaces between cylindrical specimens during triaxial testing in consolidation stage. from elevated cell pressure stage might have a negative effect on interpretation stress-strain data and specimen volume calculations shearing To assist engineers making knowledgeable judgments, additional study needed examine granitic residual soil. In this study, was investigated using modified graphical technique. Triaxial tests grade V soil were conducted as part at effective confining pressures 50 kPa, 100 200 300 400 kPa. tests, real constructed compacted with initial diameters 50mm 100mm, dummy made thin layer containing solid, rigid core, both employed. Without considering impact compression, behaviour only examined specimens. The method has be altered result fines. findings demonstrated that increased rise became less relevant kPa or lower.
