Abstract:The piled retaining wall is a new type of railway retaining structure in China. In the current design, the retaining wall, the beam and the piles are assumed to be independent components. Both the mutual action of the retaining wall, the piles and beam, and the influence of the soil or rock foundation on the structure are not fully considered, so that there are some limitations in the current design method. In this paper, using field observations and a three-dimensional finite-element analysis, the lateral earth pressure on the wall back, the stress distributions and the forces of the reinforcements in the beam and the pile were studied. The simulation results were in good agreement with the field observation data. These results revealed that the tensile stresses were very small and that these stresses were positive in most zones in the beam and the pile. It can also be observed that the tensile stresses or forces in the beam and pile obtained in this study were much smaller than those obtained using the current design method. This clarified the fact that the current design method used for the beam and the pile was very conservative and that it should be optimized to consider the effect of the foundation on the whole structure and the interactions among the different components.

Title:Pilotirani težnostni podporni zid: deformacijsko-napetostna analiza
Abstract:Pilotirani podporni zid predstavlja nov tip podpornih konstrukcij na železnicah na Kitajskem. V sedanji praksi projektiranja so podporni zid, greda in piloti obravnavani kot neodvisne komponente. Tako ni obravnavano vzajemno delovanje podpornega zidu, pilotov in grede ter ni popolnoma obravnavan vpliv zemljine ali hribine na konstrukcijo, kar predstavlja določene omejitve v veljavni metodi projektiranja. V članku je podana študija bočnih zemeljskih pritiskov na steno zidu, razporeditev napetosti ter sil v armaturi grede in pilotov, ki uporablja rezultate terenskih opazovanj in tridimenzionalnih analiz na osnovi končnih elementov. Rezultati simulacij se dobro ujemajo z rezultati terenskih meritev. Ti rezultati so pokazali, da so bile natezne napetosti zelo majhne in, da so bile napetosti v večina conah v gredi in pilotih natezne. Prav tako smo ugotovili, da so natezne napetosti ali sile v gredi in pilotu v tej študiji bile veliko manjše od nateznih napetosti dobljenih z veljavno metodo projektiranja. Razjasnili smo, da je veljavna metoda projektiranja za dimenzioniranje grede in pilotov zelo konzervativna in, da jo je potrebno optimizirati z obravnavanjem vpliva temelja na celotno konstrukcijo ter upoštevanjem interakcije vseh komponent, ki sestavljajo sistem.
