Some dynamic parameters of drilled piles under low- and high-energy tests. Correlation with the static pattern.
Guido Chiesura

The aim of this article is to present and discuss some parameters and experimental results obtained by both kinds of dynamic testing (low- and high-energy tests) on drilled piles in different sites, and some correlation between some specific dynamic and static parameters, when static tests have been carried out on the same piles. The dynamic tests are the following: (1) in the field of low-energy testing (integrity tests) the "Mobility" (or Admittance, or Vibration) method and (2) in the field of high-energy testing (capacity tests): the "Case" method. The parameters with are examined are connected with the dynamic behavior of piles; the first one (dynamic stiffness) is obtained by low-energized piles, the other (the "Dumping Factor") by high-energized piles. They have an equivalent in the static pattern of behavior. Some experimental data, obtained in different sites, are published. Correlation concern:: "Dynamic Stiffness" versus "Case Capacity" "Case Capacity" versus "Static Capacity", and they are shown graphically.
