USE OF ANALOGUES AND ANALOGIES METHOD AS A WORTHY ALTERNATIVE TO FIELD CONE PENETRATION TESTS

Abstract

Purpose. The aim is to optimize the costs of conducting engineering and geological surveys without losing the quality of design documentation.
Methods. The following were used during researches carrying out: the method of correlation of data from field development works, the method of geotechnical analogues and analogies, the collection and systematization of data from engineering surveys of past years.
Results. Analysis of the problematic of the use of static penetration test, as well as the correlation of  its results with the data of experimental field tests of piles in similar soil conditions made it possible to establish that static penetration test has a fairly wide range of application restrictions and increases the cost of performing engineering and geological surveys. At the same time, the obligation to perform the pile testing stage remains, which largely devalues the significance of the results of static penetration test.
Originality. The performed analysis allows to assert that the use of the method of geotechnical analogues and analogies is characterized by high accuracy and economic feasibility for solving the issues of foundation in well-studied soil conditions. The use of library material for piles testing makes it possible to do without expensive development survey work.
Practical implications. The proposed methodology allows optimizing the costs of performing engineering and geological surveys while allowing solving the problems of calculating pile fields effectively.
