IN SITU SHEAR STRENGTH PARAMETERS BY DUTCH CONE PENETRATION TESTS

The testing procedure is detailed and the results are presented of an effort to determine if the Dutch cone penetration testing yielded a true estimate of in situ shear strength, and to determine the manner in which the results of the testing should be interpreted. The history of the use of the test is briefly reviewed, and the test results are discussed. The in situ shear strength, as measured by triaxial tests, was shown to be approximately 80 percent of the Dutch cone sleeve friction. Further research is needed before Dutch cone data alone can be used as an accurate predictor of soil shear strength. However, the Dutch cone can predict shear strength when used in conjunction with conventional sampling and testing techniques. It is especially useful in determining the variation of shear strength with depth. Rock fragments can terminate or lead to erratic readings in the test. This tends to limit the sites at which the test can be used, or several penetrations in the vicinity of a given location may be required to obtain data.
