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 besuntswana, 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 ngaphantsi I-0.228OF ayikwazi ukwenza umaleko ongaphezulu kwe-20. Ukumila kwamasuntswana omhlaba kuya kuchaphazela iimpawu zokugcina umhlaba we-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 isalathiso 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.Izibalo-manani yenani elikhulu lezehlo zokusilela kwesihluzo se-geotextile zifumanise ukuba umaleko wesihluzo se-geotextile kufuneka uphephe ezi ndidi zomhlaba zilandelayo 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.
