1. Retaining structure in demanding ground conditions: PK-16, road Hrastnik - Zidani Most : master's thesisAleksandr Sokolov, 2021, master's thesis Abstract: The master thesis presents the findings of the review of the design documentation of PGD plans for the PK-16 retaining structure, reconstruction of the G2-108 Hrastnik - Zidani Most road and deviation of the G1-5 Rimske Toplice - Zidani Most - Radeče road.
The PK 16 retaining structure is foreseen between the Sava riverbed and the new road. The length of the retaining structure is substaintal (approx. 1140 m), the morphology of the terrain along the wall varies greatly.
However, due to the erosion of the Sava River, it is estimated that the wall will need to be deep or corrosion protection should be constructed. Temporary security and work platforms based on the Sava River Basin (which is already impounded and quite deep in this part) will be required.
The retaining structure is designed as a vertical cantilever wall that is on the underside rigidly fixed to the horizontal foundation plate. On the bulk of the structure, the foundation plate is supported by piles in two rows. The vertical wall at the top passes into a horizontal cantilever along which a corridor with a fringe runs.
The controlling calculations were done employing a computational 2D model that takes into account the elastoplastic Mohr - Coulomb model for soil and the elastic model of concrete structures.
The accompanying geotechnical calculations of the retaining structure in profiles P283 and P299 were compared with the analyses made in the design project to confirm the possibility of carrying out the proposed structures.
