METHODOLOGY OF PILE-SOIL TESTING

Abstract

The construction of pile foundations is necessary if the active layers of the soil are weak, low-strength, and compressible, that is, they are unsuitable for the construction of shallow foundations on them without improving the soil properties. Piles transfer loads from the construction to the lower usually more compacted and strong soil layers. Pile foundations have found widespread use in the difficult soil conditions of Kazakhstan. In the article, the authors present the test results of the pile bearing capacity by statically pressing load. The conditions under which the tests were carried out, the used equipment, and the measuring instruments for obtaining data on the pile loading, its condition, and behavior in the soil mass are described. This technique is effective due to the possibility of testing in various engineering and geological conditions. The obtained test results are shown in the form of graphs - dependences of settlements on loads.
