A triaxial geocomposite testing apparatus for simultaneously calibrating multiple pressure transducers

A triaxial geocomposite testing apparatus for simultaneously calibrating multiple pressure transducers are provided. The apparatus includes a base that has an inlet an outlet and a plurality of spaced apart lateral openings formed therein. A fluid having a pressure is filled within a fluid retaining section. At least one pressure transducer insertable within the fluid retaining section through a corresponding opening for providing electrical signals during testing. A pedestal is attacheable to the base and includes at least one recess formed on its top surface. The at least one recess has a first diameter and includes atleast one earth pressure transducer having a second diameter positionable therein. The first diameter is greater than the second diameter. A holding member is also disposed within the at least one recess for allowing the at least one earth pressure transducer to be tightly retained therein. Actuation surface of the at least one earth pressure transducer leveled with a top surface of the holding member .
