IN SITU TESTS AND PILE FOUNDATIONS

After mentioning possible static load tests and laboratory tests, the use of two insitu apparatus, the Dutch penetrometer and the Menard Pressiometer, in pile foundations are discussed. It is pointed out that good correlations exist between the penetrometer, the pressiometer, and in some cases, the pile driving formulas as regards end-bearing resistance. The problems of side friction, settlements and critical depth are discussed.
