WebThe Dynamic Cone Penetrometer (DCP) is used to determine underlying soil strength by measuring the device’s penetration into the soil after each hammer blow. How does a cone penetrometer work? A cone penetration … WebThis procedure gives a single measurement of the normal stress and shear stress acting on the soil at failure. In this way, the BST simulates, at least in part, the procedure used in laboratory direct shear box tests where normal stress is applied to a sample and then failure is produced by shearing the soil.

WebThe TORVANE is a hand-held vane shear device for rapid determination of shear strength in cohesive soils either in the laboratory or the field. The TORVANE allows shear … The test is suitable for clay soils classified as soft to firm. By remoulding the sample and retesting an indication of the sensitivity of the clay can also be found. The test has also been used to measure the shear strength of mortar mixes, where it has been shown to correlate with the slump value. See more The shear vane test is a method of measuring the undrained shear strength of a cohesive soil. The test is carried out with equipment consisting of a rod with vanes mounted to it that is inserted into the ground and rotated. … See more The shear vane consists of a straight rod with four vanes on one end, arranged in a cruciform pattern, and a combined handle/torque … See more The test was pioneered by L Carlson and AW Skempton in 1948. There has been some dispute over its accuracy since then. Carlson and Skempton believed that it provided a higher value than that indicated by unconfined compressive tests and in fact agreed better with … See more history of nnpp rickover
