VIBRATION TESTING

This article briefly describes the theory and presents five recent case histories of pile testing by the vibration method. Varied ground conditions, small and large diameter piles are described; in each case details are given of the background and the results are discussed. The possible cause of some serious faults found at one site is examined. Ideally the vibration testing should be planned at the design stage; the method should be used in preference to others since it measures the stiffness of the soil-pile system as well as the integrity of the concrete in the pile shaft. The author suggests that tests should be performed on the first few piles constructed to check the efficiency of the construction. Systematic checks should then be carried out on piles to compare stiffness values, those with low values may then be selected for load testing. Up to 20 piles can be tested in one day. /TRRL/
