Kutshanje, imibutho kaloliwe kwihlabathi liphela iye yabhenela ekusebenziseni i-geosynthetics njengesisombululo esinexabiso eliphantsi lokuzinzisa i-ballast.Kulo mbono, uphando olubanzi luye lwenziwa kwihlabathi jikelele ukuvavanya ukusebenza kwebhola ye-geosynthetic-reinforced phantsi kweemeko ezahlukeneyo zokulayisha.Eli phepha livavanya iinzuzo ezahlukeneyo ezinokufunyanwa lushishino lukaloliwe ngenxa yokomelezwa kwe-geosynthetic.Uphononongo loncwadi lubonisa ukuba i-geogrid ibamba ukusasazeka kwe-lateral ye-ballast, inciphisa ubungakanani besigxina sokuhlala ngokusisigxina kunye nokunciphisa ukuphuka kwamasuntswana.I-geogrid yafunyanwa kwakhona ukunciphisa ubungakanani be-volumetric compressions kwi-ballast.Ukuphuculwa kokusebenza ngokubanzi ngenxa ye-geogrid kwabonwa njengomsebenzi we-interface esebenzayo factor (φ).Ngaphezu koko, izifundo zikwaseke indima eyongezelelweyo ye-geogrids ekunciphiseni ukuhlaliswa komkhondo owahlukileyo kunye nokunciphisa uxinzelelo kwinqanaba elingaphantsi.I-geosynthetics yafunyaniswa iluncedo ngakumbi kwimeko yeengoma eziphumle kumazantsi athambileyo.Ngapha koko, izibonelelo ze-geosynthetics ekuzinziseni i-ballast zifunyenwe ziphezulu kakhulu xa zibekwe ngaphakathi kwe-ballast.Indawo efanelekileyo yokubeka i-geosynthetics ichazwe ngabaphandi abaninzi malunga ne-200-250 mm ngaphantsi kwe-soffit yokulala ye-ballast yesiqhelo ye-300-350 mm.Inani lophando lwemimandla kunye nezikimu zokubuyisela kwisimo sangaphambili ziqinisekise indima ye-geosynthetics/geogrids ekuzinziseni amathrekhi ngaloo ndlela inceda ekususeni izithintelo ezingqongqo zesantya ebezibekwe ngaphambili, kunye nokwandiswa kwexesha phakathi kwemisebenzi yolondolozo.
