20.500.12556/DKUM-70503 Analytical method for the analysis of stone-columns according to the Rowe dilatancy theory Analitična metoda za analizo gruščnatih kolov z upoštevanjem Rowove teorije razmikanja In this paper a new analytical method to analyse the behaviour of rigid foundations stabilized by end bearing stone-columns is proposed. The stone column and the surrounding soil are treated in axial symmetric conditions as a unit cell. The stone column is assumed to behave as an Mohr-Coulomb rigid-plastic material with non-associative flow rule according to the Rowe stress dilatancy theory and the soil as an elastic material. These common assumptions, combined with equilibrium and kinematic conditions, lead to the simple analytical closed-form solution for the prediction of the behaviour for rigid footings resting on stone-column reinforced ground. The parametric study is presented to show the effect of dilatancy of the granular material on the deformations and stresses in the ground and its beneficial effect on settlement reduction. The results of the new method are compared with some already known analytical methods and some published field test results and observations. V članku je predstavljena nova metoda za analizo obnašanja togih temeljev na z gruščnatimi koli izboljšanih tleh. Gruščnat kol in okolna zemljina sta analizirana v pogojih osne simetrije kot enotna celica. Za gruščnat kol je predpostavljeno, da se obnaša kot Mohr-Coulombov togo-plastičen material z upoštevanjem neasociativnega tečenja po Rowovi teoriji razmikanja. Za zemljino je privzeto, da se obnaša kot linearno elastičen material. Te predpostavke, skupaj z ravnotežnimi in kinematičnimi enačbami, vodijo k preprosti analitični rešitvi za napoved obnašanja togih temeljev na z gruščnatimi koli stabiliziranih tleh. Prikazana je parametrična študija, ki analizira vpliv razmikanja gruščnatega materiala na deformacije in napetosti v temeljnih tleh ter ugoden vpliv na redukcijo posedkov. Rezultati nove metode so primerjani z nekaterimi drugimi analitičnimi metodami in objavljenimi rezultati terenskih testov in opazovanj. ground improvement stone columns ground settlements dilatancy theory izboljšanje tal gruščnati koli posedki tal teorija razmikanja true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-05-17 09:30:36 2018-05-17 09:32:08 2022-08-01 19:25:20 2019-07-11 18:09:19 2006 0 0 str. 36-45 št. 1 Letn. 3 2006 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 624.12/.14 215987712 3148641 1854-0171 URN:SI:UM:DK:BTFYER3D Acta_geotechnica_Slovenica_2006_Pulko,_Majes_Analytical_Method_for_the_Analysis_of_Stone-Columns_According_to_the_Rowe_Dilatancy_Theory.pdf Acta_geotechnica_Slovenica_2006_Pulko,_Majes_Analytical_Method_for_the_Analysis_of_Stone-Columns_According_to_the_Rowe_Dilatancy_Theory.pdf 1 780595326325B698495AC6024419EC37 5b30772b3d72575e0b6648d2c939e65cc54e19007e8376713d12b5ce96e1a28e f621cc7d-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/37ecbae2-8eec-4d57-8e89-606ee04a854e https://dk.um.si/Dokument.php?lang=slv&id=124783 http://fgserver3.fg.um.si/journal-ags/2006-1/article-3.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=124782 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
