The acrylic tube, referred to as geocell in this paper, is 2.19m long with an inner diameter of 280mm. Both ends of the acrylic tube were covered with permeable geotextile sheets to allow water dissipation. The dredged soil fill material is hydraulically filled into the acrylic tube in the form of soil-water mixture (slurry). Load cells oriented in the vertical and horizontal directions were installed inside the geocell to measure the horizontal and vertical pressures inside the cylindrical tube. The pressure readings are collected through a data logger and interpreted by a desktop computer. The pressure distribution inside the geocell based on the load cell readings are closely related to the theoretical Ko and Ka conditions.
