Abstract
Field testing of laterally loaded single piles and group of piles in natural sandy gravels is presented. Testing is performed on monotonically loaded single pile, cyclicly loaded single pile, group of 2 by 1 piles monotonically loaded and group of 2 by 3 piles monotonically loaded. During the field testing, pile deflections were measured using inclinometer probe, which was placed in inclinometer casings installed in pile axis. Tests are performed for establishment of pile behaviour in natural sandy gravels and to try to depict the influence of dilatancy, in this type of soil material. Soil is tested in large direct shear box in order to obtain strength parameters needed for calculation of p-y curves proposed by Reese and Van Impe and for numerical analysis, by using simple Mohr-Coulomb and Drucker-Prager constitutive models. Piles are loaded with hydraulic press, counter-bracing the massive concrete block, which will transfer the load on a steel frame and pile heads thus pulling the piles away from concrete block. Performed tests can be described as displacement control tests. Piles are displaced in increments of 2mm while the force on hydraulic press will be read out for each increment. Measured results are compared with results of numerical analyses performed using Rocscience RS3 software package. Pile and soil material are described using Mohr-Coulomb constitutive material using associated and non-associated flow behaviours for soil material. Based on field tests and numerical analyses, the conclusions and further research in the field of laterally loaded piles in coarse-grain material are presented.
Abstract (croatian)
U radu su prikazana terenska ispitivanja na horizontalo opterećenim pilotima izvedenim u prirodnim pjeskovitim šljuncima. Ispitivanja su provedena na jednom monotono opterećenom pilotu, jednom ciklički opterećenom pilotu, grupi od dva monotono opterećena pilota u nizu (dva reda i jedan stupac) i grupi od šest monotono opterećenih pilota (dva reda i tri stupca). Tijekom ispitivanja deformacije pilota mjerene su inklinometarskom sondom, koja se upuštala u inklinometarsku cijev izvedenu kroz uzdužnu os pilota. Ispitivanja su provedena kako bi se dobio uvid u ponašanje pilota u prirodnim pjeskovitim šljuncima te da li na ponašanje utječe dilatancija, u ovakvom materijalu. Materijal je ispitan smicanjem u velikom aparatu za izravan posmik kako bi se dobili parametri čvrstoće potrebni za proračun p-y krivulja prema Reesu i Van Impeu, ali i za primjenu numeričkog modela, korištenjem konstitutivnih modela prema Mohr-Coulombu ili Drucker-Prageru. Piloti su opterećeni hidrauličkom prešom, razuprtom o masivni betonski blok, te prenoseći opterećenje na glave pilota ˇcime se piloti pomiču od betonskog bloka. Ispitivanja se mogu okarakterizirati kao ispitivanja s kontroliranim pomakom. Piloti su pomicani u inkrementima od 2mm, a sila na preši se očitavala za svakiinkrement. Dobiveni rezultati mjerenjem usporedeni su s rezultatima numeričkih analiza dobivenih korištenjem Rocsceience programskog paketa RS3. Pilot i materijal tla opisani su Mohr-Coulombovim konstitutivnim zakonom uz korištenje pridruženog i nepridruženog tečenja kod opisivanja ponašanja tla. Na osnovu in-situ ispitanih pilota i provedenih numeričkih analiza dani su zaključci te preporuke za daljnja istraživanja o ponašanju horizontalno opterećenih pilota u krupnozrnatim materijalima.
