Abstract

Piles testing for determination of their bearing capacity performs by applying a load with measurement of the value of settlement on its head. By standard pile test, it is impossible to determine the value of shear resistance along the shaft of a pile and a compression below its toe. The new test procedure allows to determine the values of these characteristics. Tests were performed using equipment for standard pile tests. The essence of the developed method is to use the elastic properties of the soil and pile material to estimate characteristics of soil resistance. For this purpose, instead of the stepwise-increasing method was applied cyclically increasing load. Each stage represents an independent cycle, consisting of the load application, holding it up to the stabilization of strains and unloading stage.
