Izici zenhlabathi evikelwe zinomthelela ekusebenzeni okungahambisani nokuhlunga. I-geotextile ngokuyinhloko isebenza njenge-catalyst kungqimba oluphikisana nokuhlunga, okukhuthaza ukwakheka kongqimba olungaphezulu kanye nongqimba lwesihlungi semvelo phezulu kwe-geotextile. Isendlalelo sesihlungi semvelo sidlala indima ekulweni nokuhlunga. Ngakho-ke, izakhiwo zenhlabathi evikelwe zinomthelela obalulekile ezicini zesihlungi esihlanekezelwe. Lapho usayizi wezinhlayiya zenhlabathi ulingana nosayizi wembotshana we-geotextile, kungenzeka ukuthi uvimbele ku-geotextile.
I-Geotextiles idlala indima enkulu kakhulu kusihlungi esihlanekezelwe
I-nonuniformity coefficient yenhlabathi imelela ukungafani kosayizi wezinhlayiyana, kanye nesilinganiso sosayizi wezinhlayiyana oyisici se-geotextile OF kuya kusayizi wezinhlayiyana eziyisici esingu-DX wenhlabathi kufanele zilandele i-nonuniformity coefficient C μ Ukwanda nokuncipha, kanye nezinhlayiya zenhlabathi ezinosayizi wezinhlayiyana ezingaphansi. 0.228OF ayikwazi ukwenza ungqimba olungaphezulu 20. Ukuma kwezinhlayiya zomhlabathi kuzothinta izici zokugcinwa kwenhlabathi i-geotextile. Ukuskenwa kwe-electron microscope kukhombisa ukuthi itailings inezici ezisobala ze-eksisi ende nezimfushane, ezibangela i-anisotropy iyonke yemisila. Kodwa-ke, asikho isiphetho esicacile somthamo ethonyeni lokuma kwezinhlayiyana. Umhlabathi ovikelwe okulula ukubangela ukwehluleka kwesihlungi esihlanekezelwe unezici ezithile ezijwayelekile.

I-German Society of Soil Mechanics and Basic Engineering ihlukanisa inhlabathi evikelekile ibe inhlabathi eyinkinga kanye nomhlabathi ozinzile. Inhlabathi eyinkinga ngokuyinhloko inhlabathi enodaka oluningi, izinhlayiya ezinhle kanye nokuhlangana kancane, okunezici ezilandelayo: ① inkomba yepulasitiki ingaphansi kuka-15, noma isilinganiso sobumba/nodaka singaphansi kuka-0.5; ② Okuqukethwe kwenhlabathi enosayizi wezinhlayiyana phakathi kuka-0.02 no-0.1m kungaphezu kuka-50%; ③ I-coefficient engalingani C μ Ngaphansi kuka-15 futhi iqukethe izinhlayiya zobumba nodaka. Izibalo zenani elikhulu lezimo zokuhluleka kwesihlungi se-geotextile zithole ukuthi isendlalelo sesihlungi se-geotextile kufanele sigweme izinhlobo zenhlabathi ezilandelayo ngangokunokwenzeka: ① inhlabathi engahlangani enohlamvu olucolekile olunosayizi owodwa wezinhlayiyana; ② Inhlabathi engahlangani ephukile; ③ Ubumba oluhlakazekayo luzohlakazeka lube yizinhlayiya ezinhle ezihlukene ngokuhamba kwesikhathi; ④ Umhlabathi ocebile nge-iron. Ucwaningo lwe-Bhatia lwalukholelwa ukuthi ukungazinzi kwangaphakathi kwenhlabathi kubangele ukwehluleka kwesihlungi se-geotextile. Ukuzinza kwangaphakathi kwenhlabathi kusho amandla ezinhlayiya ezimahhadla ukuvimbela izinhlayiya ezinhle ukuthi zingathwalwa wukugeleza kwamanzi. Kuye kwakhiwa izindlela eziningi zokucwaninga ukuzinza kwangaphakathi kwenhlabathi. Ngokuhlaziywa nokuqinisekiswa kwemibandela eyi-131 ejwayelekile yamasethi edatha yesibaluli senhlabathi, kuhlongozwa izindlela ezengeziwe ezisebenzayo.
