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 Ukwandisa nokuncipha, kanye nezinhlayiya zenhlabathi ezinosayizi wezinhlayiyana ezingaphansi 0.228OF ayikwazi ukwakha ungqimba olungaphezulu 20. Ukuma kwezinhlayiya zomhlabathi kuzothinta izici zokugcinwa kwenhlabathi ze-geotextile.Ukuskena kwe-electron microscope kukhombisa ukuthi itailings inezici ezisobala ze-eksisi ende nezifushane, 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.
