Ala geoloogiline ehitus on keeruline - maantee on ehitatud kuni 4 m paksusele turbakihile, mis on aja jooksul konsolideerunud ning vajunud 1,85…2,05 m ulatuses. Oja säng on aga oli koormamata ning turvas vahetult silla all on tihendamata. Vastavalt pöördarvutusele on tihendamata turba deformatsiooni moodul E=0,13 MPa , millele on iseloomulik turba dreenimata nihketugevus Cu =11…12 kPa . Konsolidatsiooni protsessi käigus on turvas tihenenud ning tema dreenimata nihketugevus võiks kasvata kuni Cu =15 kPa . Truubi rajamisel vajub uus rajatis ebaühtlaselt kohtades, kus turvas on konsolideeriamta . Vajumid ulatuvad kuni 1,7 meetrini ning see protsess kestab intensiivselt kuni 0,5…1 aasta ( Cv =10 m2/aasta). Edaspidi vajumid aeglustuvad, kuid ei lõpe. Üks võimalus vältida ebaühtlaseid deformatsioone on eemaldada turvas ning asendada mineraal pinnasega. Selleks rajatava süvendi sügavus on 4,6 m ning käesoleva töö käigus kontrolliti süvendi seinte stabiilsus kahe kallakuse juures 1:1,5 ja 1:2. Mõlema kallakuse puhul stabiilsus pole tagatud ja püsivustegur on ühele lähedane.

Esialgsel hinnangul sulundseina elementide pikkus peab olema ca 8 m ning võib koosneda näiteks profiilist GU6N. Soodsam on rajada nn „sõdurseina“, kus H talad suvitatakse ca 1 m sammuga ning nende vahed täidetakse puitprussidega.

Project no.:2011628-1E-SAR
The lower reinforcement layer is Fortrac R 400‐50‐30 T (has to be wrapped around in the transverse
direction).
The upper reinforcement layer is Fortrac R 300‐50‐30 T in the longitudinal direction.
The adjacent reinforcement layers have to 50 cm overlapped above the pile plate.
The applied load on the pile is 138.29 kN.
It is assumed, that a pile cap (reinforced concrete) with a diameter of 50 cm is installed on top of
each pile to avoid deformation deformation due to punching.
