Abstract

Cilj ovog rada bila je analiza i usporedba utjecaja nagiba štapnih sidara na stabilnost zaštitne konstrukcije. Analiza rezultata napravljena je programskom paketu Plaxis, a proučavana su tri slučaja različitih nagiba sidra. U slučaju A pasivna sidra su duljine 6 m pod nagibom od 35°, u slučaju B pasivna sidra su duljine 6 m pod nagibom od 25° te u slučaju C pasivna su sidra duljine 6 m pod nagibom od 15°. Prikazane su teorijske osnove i vrste potpornih i zaštitnih konstrukcija, detaljnije su opisane zaštitne konstrukcije koje su bile tema ovog rada (sidra i mikropiloti), opisana je lokacija stambene zgrade koja služi kao podloga za analizu utjecaja nagiba sidra, prikazani su geotehnički istražni radovi i laboratorijska ispitivanja. Analizirani i uspoređivani su utjecaji nagiba sidra na dobivene vrijednosti horizontalnih pomaka pilota zaštitne konstrukcije, na vrijednosti momenata savijanja pilota zaštitne konstrukcije, na vrijednosti uzdužnih pomaka sidara te na vrijednosti uzdužne sile u sidrima. Analizom rezultata dobivenih za sva tri slučaja zaključeno je kako se najveća odstupanja javljaju u slučaju B, a u slučaju A i C rezultati su vrlo sličnih vrijednosti.

Abstract (english)

The aim of this study was to analyze and compare the influence of the inclination of passive ground anchors on the stability of the protective structure. The results were analyzed using the Plaxis software package and three cases of different anchor inclinations were studied. In case A, the passive anchors are 6 m long at an inclination the 35°, in case B, the passive anchors are 6 m long at an inclination of 25°and in case C, the passive anchors are long 6 m at an inclination of 15°. The theoretical background and the types of supporting and protective structures are presented. The protective structures that were the subject of this study (anchors and micropiles) are desribed. The location of the residental building is described to serve as a basis for the analysis along with the presentation of influence of the anchor's inclination, geotehnical investigation works and laboratory tests. The primary analysis and comparison was between the influence of the anchor's inclination on the obtained values of the horizontal displacements of the piles of the protective structure, on the values of the bending moments of the piles of the protecite structure, on the values of the longitudinal displacement of the anchors and on the values of the longitudinal force in the anchors. When analyzing the results for all three cases it was found that the largest deviations occur in case B while in cases A and C the reuslts are of very similar.
