AbstractAbout AuthorsReferences
The concrete strength of cross-section of bored-injection EDT-piles is a fundamental index for determination of bearing capacity by soil and by shaft. Electric discharge technology makes it possible to increase the strength of fine concrete. Also it can exceed the strength of untreated concrete by 40–50% by using the electro-hydraulic method. An important role in the process of development of strength in concrete plays a compliance with technological regulations of EDT-piles manufacturing. Cases of the inconsistency of concrete strength with design values are very frequent in geotechnical construction. In the article below a case of geotechnical practice is given.
