CONSIDERATIONS ON METHOD FOR AXIAL STATIC COMPRESSIVE LOAD TEST OF SINGLE PILES

Abstract

In the static axial compressive load tests of a single pile, various methods are in existence, i.e.; the direct loading method, the method using reaction piles, the method using masses as loading reaction, the pile-toe loading method and so on. However, in these methods, influence of the loading reaction has not been compared and discussed enough. We carried out various load tests of model piles in order to examine the above problems. From these results, we could understand that the initial rigidities of compressive loads are evaluated larger and the ultimate bearing capacities are evaluated smaller in the cases of using reaction devices.
