Statnamic pile testing for foundation re-use

Statnamic testing is intended to verify a pile’s load settlement characteristics quickly and without the need for knowledge of pile quality or integrity. The advantages and disadvantages of Statnamic deployment in pile re-use studies with respect to static and dynamic testing are identified. Results from full-scale Statnamic testing in London Clay are presented. The results and performance of two techniques to predict equivalent static pile resistance from Statnamic test data are compared with the results of maintained load static testing. The need to include rate parameters related to the soil type is shown. In order to allow accurate assessment of pile capacity it is shown that significant displacements need to be generated and loads significantly greater than those applied in static testing need to be applied.
