| Abstract: | A study on pressure calibration of a triaxial testing apparatus with solid confining media is presented with temperature up to 625℃ and confining pressure up to 6.5kb. The solid confining media used were Pb,AgCl and Nacl. For room temperature, phase-transition materials, such as NH4I, phenol, AgI, NH4F and KNO2 were used to establish the relationship between the pressure applied on the specimen and the nominal pressurre measured outside The vessel. The correction of confining pressure △σc changi |
