Abstract

Potporne konstrukcije imaju ulogu u pridržanju okolnog tla s ciljem održavanja stabilnosti. Prometna infrastruktura, točnije prometnice su vrlo važan, svakodnevni dio čovjekovog djelovanja, a problematika istih se očitava i u problemima nastalih zbog klizišta, čija je pojava sve učestalija. U ovom radu, prikazat će se sanacija klizišta na ulazu u naselje Tkalci. Klizište je nastalo na državnoj cesti DC206, na cesti u zasjeku, zbog klizanja materijala na nizbriježnoj padini. Prikazat će se početno stanje naprezanja zahvatom obuhvaćene ceste, zajedno s geotehničkim karakteristikama tla i sanacijskim rješenjem, potvrđenim pomoću prikazanih geotehničkih proračuna. Uz navedeno, prikazat će se istražni radovi i terenska ispitivanja, pomoću kojih se klasificiralo tlo na promatranom području. Uzimajući u obzir da se sanira državna cesta odabrano sanacijsko rješenje je potporna konstrukcija izvedena kao pilotna stijena s konzolnim zidom. Prikazat će se proračun i dimenzioniranje pilotne stijene i konzolnog zida, kao i tehnički uvjeti izvedbe.

Abstract (english)

Supporting structures have the role of retaining the surrounding soil in order to maintain stability. Transportation infrastructure, specifically roadways, are a very important and daily part of human activity, and their issues are evident in the problems caused by landslides, which are becoming increasingly frequent. This paper will present the remediation of a landslide at the entrance to the Tkalci settlement. The landslide occurred on the state road DC206, on a road in a cut, due to material sliding on the downslope. The initial stress state of the affected road section will be shown, along with the geotechnical characteristics of the soil and the remediation solution confirmed by the presented geotechnical calculations. Additionally, the investigative work and field tests will be presented, through which the soil in the observed area was classified. Considering that a state road is being remediated, the chosen remediation solution is a supporting structure implemented as a soldier pile wall with a cantilever wall. The design and dimensioning of the soldier pile wall and cantilever wall, as well as the technical execution requirements, will be presented.
