Test results of bored piles

Abstract

Tests of bored piles in two sites have been performed using the weight of multistory buildings as a static load. Three objectives of tests have been formulated as follows: to approve specific test methodology, to compare bearing capacity of piles obtained from calculation with those from tests and to verify specific technology of pile installation. In the article the results of tests are presented, discussed and evaluated. One 24 floor height building was erected above Gelezinio Vilko street, near the City centre of Vilnius. The space under the building was used to elongate the already existing 290 m tunnel by adding a 100 meter section. Another test site was in Klaipeda, where bored piles were installed for a new 34 floor building constructed near the city center close to the seashore. Test results approved all the raised assumptions.
