Pressure chamber testing of model caisson foundations in sand
Various aspects of tensile vertical capacity of the caisson foundations in sand were discussed. A model caisson having a diameter of 280mm and a skirt depth of 180mm and a waterproof load cell was used to measure the axial load on the caisson and any moment loads occured during loading.

| Summary: | Various aspects of tensile vertical capacity of the caisson foundations in sand were discussed. A model caisson having a diameter of 280mm and a skirt depth of 180mm and a waterproof load cell was used to measure the axial load on the caisson and any moment loads occured during loading. The pressure chamber comprised a watertight cylindrical vessel and a saturated sand sample was placed inside the pressure chamber to a height of about 560nm above a perforated false floor. It was observed that a soil plug remained inside the skirts of the caisson after the caisson is fully extracted from the sand. |
