WebBearing capacity is the ability of the underlying soil to support the foundation loads without shear failure. Bearing capacity factors are empirically derived factors used in a bearing capacity equation that usually correlates with the angle of internal friction of the soil. See the bearing capacity technical guidance for equations and detailed ... WebThe modulus is an indicator for the bearing capacity of the soil or flexible pavement under the loading plate. For the test, the soil is loaded and unloaded in fixed steps using a circular loading plate and a hydraulic loading device. The load plate is loaded by a hydraulic jack and it’s settlement is measured at increasing load increments.
