Iimpawu zomhlaba okhuselweyo zinempembelelo ekusebenzeni okuchasene nokuhluzwa. I-geotextile ikakhulu isebenza njenge-catalyst kwi-anti-filtration layer, ekhuthaza ukubunjwa kwe-overhead layer kunye ne-natural filter layer in the upstream of geotextile. Uluhlu lokucoca lwendalo ludlala indima ekuchaseni ukuhluzwa. Ngoko ke, iipropati zomhlaba okhuselweyo zineempembelelo ezibalulekileyo kwiimpawu zefayile eguqulweyo. Xa ubungakanani bamasuntswana omhlaba bulingana nobukhulu bepore ye-geotextile, kunokwenzeka ukuba buthintele kwi-geotextile.
Ii-geotextiles ikakhulu zidlala indima ebambekayo kwisihluzi esijikiweyo
I-nonuniformity i-coefficient yomhlaba imele i-nonuniformity yobungakanani bamasuntswana, kunye nomlinganiselo wephawu lobungakanani bepore ye-geotextile OF ukuya kuphawu lobungakanani besuntswana le-DX lomhlaba kufuneka lilandele i-nonuniformity coefficient C μ Yandisa kwaye icuthe, kunye namasuntswana omhlaba anesayizi yamasuntswana angaphantsi 0.228OF ayikwazi ukwenza umaleko ongaphezulu 20. Ukumila kwamasuntswana omhlaba kuya kuchaphazela iimpawu zokugcina umhlaba geotextile. Ukuskena imakroskopu ye-electron kubonisa ukuba iintsalela zezimbiwa zineempawu ezicacileyo ze-axis ezinde nezimfutshane, ezibangela i-anisotropy iyonke yomsila. Nangona kunjalo, akukho sigqibo esicacileyo sobungakanani kwimpembelelo ye-particle shape. Umhlaba okhuselweyo kulula ukubangela ukusilela kwesihluzo esiguqulweyo sineempawu eziqhelekileyo.
Ii-geotextiles ikakhulu zidlala indima ebambekayo kwisihluzi esijikiweyo
I-German Society of Soil Mechanics kunye ne-Basic Engineering yahlula umhlaba okhuselweyo ube ngumhlaba oyingxaki kunye nomhlaba ozinzileyo. Umhlaba onengxaki ubukhulu becala ngumhlaba onentlenga ephezulu, amasuntswana amahle kunye nokudityaniswa okuphantsi, okunenye yezi mpawu zilandelayo: ① isalathisi seplastiki singaphantsi kwe-15, okanye umlinganiselo wodongwe / wentlenga ungaphantsi kwe-0.5; ② Isiqulatho somhlaba onobungakanani bamasuntswana phakathi kwe-0.02 kunye ne-0.1m ngaphezulu kwe-50%; ③ Umlinganiso ongalinganiyo C μ Ngaphantsi kwe-15 kwaye iqulethe udongwe kunye namasuntswana entlenga. Iinkcukacha-manani yenani elikhulu lezehlo zokusilela kwesihluzo se-geotextile zifumanise ukuba umaleko wesihluzo se-geotextile kufuneka uphephe ezi ndidi zilandelayo zomhlaba kangangoko kunokwenzeka: ① umhlaba ongadityanisiweyo ocolekileyo onobukhulu besuntswana elinye; ② Umhlaba odityanisiweyo owaphukileyo; ③ Udongwe olusasazwayo luya kuthi saa lube ngamasuntswana alungileyo ahlukeneyo ngexesha; ④ Umhlaba otyebileyo ngeeayoni zentsimbi. Uphononongo lwe-Bhatia lwalukholelwa ukuba ukungazinzi kwangaphakathi komhlaba kubangele ukusilela kwesihluzo se-geotextile. Ukuzinza kwangaphakathi komhlaba kubhekiselele kubuchule bamasuntswana arhabaxa ukuthintela amasuntswana amahle ukuba angathwalwa kukuhamba kwamanzi. Iikhrayitheriya ezininzi zenziwe ukuze kufundwe uzinzo lwangaphakathi lomhlaba. Ngokuhlalutya kunye nokuqinisekiswa kwe-131 inqobo yokulinganisa eqhelekileyo kwiiseti zedatha yophawu lomhlaba, iindlela ezisebenzayo ezingaphezulu ziye zacetywa.
