Abstract:This paper proposes a new method for the geomechanical analysis and design of cantilever retaining structures. It is based on the limit equilibrium method, but it uses some additional conditions for interaction between the retaining structure and the ground, when referring to the distribution of the mobilized earth pressures on the structure. The greatest benefit of the proposed method is shown in the analysis of structures of layered ground (heterogeneous above the dredge level and homogeneous below it), embedded in frictional and cohesive materials, and in the possibility of considering the influence of surcharge loadings on the active or passive side of the retaining structure. When analyzing such cases in practice, the proposed method gives results which are in better agreement with the results of FEM based elasto-plastic interaction analyses than with the results of currently used methods. At the same time, its results are in accordance with those published for homogeneaus cohesionless ground. Since in practice almost all retaining structures are erected in layered ground (heterogeneaus above the dredge level and homogeneous below it), the proposed method is very convenient and applicable for the analyses and design of cantilever structures under arbitrary geomechanical conditions.

Title:Interakcijska analiza konzolno vpetih podpornih konstrukcij
Abstract:V članku so prikazane metode za geomehanske analize in projektiranje konzolnih podpornih konstrukcij. Vse podane rešitve temeljijo na metodi mejnih stanj in so uporabne pri analizah podpornih konstrukcij v tleh poljubnih geomehanskih lastnosti. Prikazana je posplošitev nekaterih obstoječih metod, ki temeljijo na predpostavki linearne porazdelitve vplivov in odporov, vendar za nekatere standardne primere nehomogenih tal ne dajejo zanesljivih rezultatov. Zato je podan predlog nove izboljšane metode, ki prav tako temeljina analizi mejnih stanj, vendar so pri razporeditvi aktiviranih vplivov in odporov upoštevane nekatere dodatne interakcijske soodvisnosti med podpornimi konstrukcijami in tlemi. Prednosti predlagane metode se kažejo predvsem pri analizah konstrukcij v heterogenih tleh, vpetosti v koherentne materiale in možnostih upoštevanja vplivov berme pred ter dodatnih površinskih obremenitev v zaledju podpornih konstrukcij. V takšnih bolj realnih primerih predložena metoda daje rezultate, ki so skladnejši z rezultati primerljivih elasto-plastičnih interakcijskih analiz po metodi končnih elementov ter so hkrati skladni tudi z rezultati že v literaturi objavljenih rešitev za primere v homogenih nekoherentnih tleh. Ker se v praksi skoraj vse podporne konstrukcije nahajajo v nehomogenih tleh, obstoječe metode pa dajejo natančne rešitve le za podporne konstrukcije v homogenih in nekoherentnih tleh, so prikazane rešitve bolj primerne in bolj uporabne za analize in projektiranje vpetih podpornih konstrukcij v geotehnični praksi.
