Gcwalisa inhlabathi Gcwalisa inhlabathi inhlabathi efakwe ngokugcwaliswa nge-hydraulic.Eminyakeni yamuva nje, ibisetshenziswa kabanzi ekuthuthukisweni kwamagagasi asogwini kanye nokulungiswa kabusha kwezindawo zezikhukhula.Idamu eliwa amanzi (elibizwa nangokuthi i-fill dam) elivame ukubonakala esifundeni esisenyakatho-ntshonalanga yidamu elakhiwe ngenhlabathi egcwele.Isisekelo esakhiwe ngokugcwalisa inhlabathi singabhekwa njengohlobo lwesisekelo semvelo.Izakhiwo zayo zobunjiniyela ngokuyinhloko zincike ezintweni zenhlabathi yokugcwalisa.Gcwalisa isisekelo senhlabathi ngokuvamile sinezici ezibalulekile ezilandelayo.(1) I-particle sedimentation ngokusobala ihlungiwe.Eduze nendawo yokufaka udaka, izinhlayiya ezimahhadla zifakwa kuqala.Kude nendawo yokufaka udaka, izinhlayiya ezifakwe emanzini ziba ngcono.Ngesikhathi esifanayo, kukhona i-stratification ecacile ekuqondeni kokujula.(2) Okuqukethwe kwamanzi enhlabathini yokugcwalisa kuphakeme ngokuqhathaniswa, ngokuvamile kukhulu kunomkhawulo woketshezi, futhi isesimweni esigelezayo.Ngemva kokumiswa kokugcwalisa, ubuso buvame ukuqhekeka ngemva kokuhwamuka kwemvelo, futhi okuqukethwe kwamanzi kuncipha kakhulu.Kodwa-ke, inhlabathi yokugcwalisa ephansi isasesimweni esigelezayo lapho izimo zokukhipha amanzi zingezinhle.Ukuqina kwezinhlayiya zenhlabathi egcwele, kusobala kakhulu lesi simo.(3) Amandla okuqala esisekelo somhlabathi wokugcwalisa aphansi kakhulu futhi ukucindezelwa kuphakeme kakhulu.Lokhu kungenxa yokuthi inhlabathi yokugcwalisa isesimweni esingaqinisiwe.Isisekelo se-backfill kancane kancane sifinyelela esimweni esivamile sokuhlanganisa njengoba isikhathi esimile sikhula.Izakhiwo zayo zobunjiniyela zincike ekwakhekeni kwezinhlayiyana, ukufana, izimo zokuhlanganisa amanzi kanye nesikhathi esimile ngemva kokugcwalisa emuva.
4. Isihlabathi esinenhlabathi eyisihlabathi esigcwele udaka noma isisekelo sesihlabathi esicolekile sivame ukuba namandla aphezulu ngaphansi komthwalo ongashintshi.Kodwa-ke, lapho umthwalo wokudlidliza (ukuzamazama komhlaba, ukudlidliza komshini, njll.) kusebenza, isisekelo senhlabathi enesihlabathi esigcwele esixegayo singancibilika noma sibe nenani elikhulu lokuguquguquka kokudlidliza, noma silahlekelwe amandla okuthwala.Lokhu kungenxa yokuthi izinhlayiya zenhlabathi zihleleke ngokuxekethile futhi indawo yezinhlayiya iyasuswa ngaphansi kwesenzo samandla ashukumisayo angaphandle ukuze kuzuzwe ibhalansi entsha, edala ngokushesha umfutho wamanzi wembotshana owedlulele futhi ukucindezeleka okusebenzayo kuncipha ngokushesha.Inhloso yokwelapha lesi sisekelo ukwenza kube compact kakhudlwana futhi kuqedwe ukuthi kungenzeka uketshezi ngaphansi komthwalo oguquguqukayo.Izindlela zokwelapha ezivamile zihlanganisa indlela ye-extrusion, indlela ye-vibroflotation, njll.
5. I-Collapsible loess Umhlabathi owenza ukuguqulwa okuphawulekayo okwengeziwe ngenxa yokubhujiswa kwesakhiwo senhlabathi ngemva kokucwiliswa ngaphansi kokucindezeleka okuzithwala kwengqimba yenhlabathi engaphezulu, noma ngaphansi kwesenzo esihlangene sokucindezeleka kwesisindo nokucindezeleka okwengeziwe, kubizwa ngokuthi i-collapsible. umhlabathi, okungowomhlabathi okhethekile.Eminye inhlabathi egcwele ingxubevange nayo iyagoqeka.Ukulahlekelwa okusatshalaliswa kabanzi eNyakatho-mpumalanga yezwe lami, eNyakatho-ntshonalanga ye-China, e-Central China nasezingxenyeni ze-East China kuyagoqeka kakhulu.(I-loess okukhulunywe ngayo lapha ibhekisela enhlabathini efana ne-loess. I-Collapsible loess ihlukaniswa ngokwesisindo esigoqekayo kanye ne-non-self-weight collapsible loess, kanti enye i-loess endala ayigoqeki).Lapho wenza ukwakhiwa kobunjiniyela ezisekelweni ze-loess ezigoqekayo, kuyadingeka ukuthi kubhekwe umonakalo ongaba khona kuphrojekthi obangelwe ukuwohloka kwesisekelo, futhi ukhethe izindlela zokwelapha eziyisisekelo ezifanele ukugwema noma ukuqeda ukuwa kwesisekelo noma ukulimala okudalwe inani elincane lokuwa.
6. Inhlabathi enwetshiwe Ingxenye yamaminerali yenhlabathi enwetshiwe ngokuyinhloko i-montmorillonite, ene-hydrophilicity eqinile.Iyanda ngevolumu lapho imunca amanzi futhi incipha ngevolumu lapho ilahlekelwa amanzi.Lokhu kunwebeka nokuncipha kuvame ukuba kukhulu kakhulu futhi kungabangela kalula umonakalo ezakhiweni.Inhlabathi enwetshiwe isatshalaliswa kabanzi ezweni lami, njengeGuangxi, Yunnan, Henan, Hubei, Sichuan, Shaanxi, Hebei, Anhui, Jiangsu nezinye izindawo, ngokusatshalaliswa okuhlukile.Inhlabathi enwetshiwe iwuhlobo olukhethekile lomhlabathi.Izindlela ezijwayelekile zokwelashwa kwesisekelo zihlanganisa ukubuyisela umhlabathi, ukuthuthukiswa kwenhlabathi, ukucwiliswa ngaphambili, kanye nezinyathelo zobunjiniyela zokuvimbela izinguquko kokuqukethwe komswakama kwesisekelo senhlabathi.
7. Inhlabathi ephilayo kanye ne-peat Inhlabathi Lapho inhlabathi iqukethe izinto eziphilayo ezihlukene, kuyokwakhiwa inhlabathi ehlukahlukene yemvelo.Lapho okuqukethwe kwe-organic matter kudlula okuqukethwe okuthile, inhlabathi ye-peat izokwakhiwa.Inezici zobunjiniyela ezahlukene.Ukuphakama kokuqukethwe kwe-organic matter, kuba nomthelela omkhulu kukhwalithi yenhlabathi, ebonakala kakhulu ngamandla aphansi kanye nokucindezelwa okuphezulu.Iphinde ibe nemiphumela ehlukene ekufakweni kwezinto ezihlukene zobunjiniyela, okunomthelela omubi ekwakhiweni kobunjiniyela obuqondile noma ukwelashwa kwesisekelo.
8. Inhlabathi yesisekelo sezintaba Izimo ze-geological zenhlabathi yesisekelo sezintaba ziyinkimbinkimbi ngokuqhathaniswa, zibonakaliswa ngokuyinhloko ngokungalingani kwesisekelo kanye nokuzinza kwesayithi.Ngenxa yethonya lendawo yemvelo kanye nezimo zokwakheka kwesisekelo senhlabathi, kungase kube namadwala amakhulu endaweni, futhi indawo yendawo ingase ibe nezimo ezingezinhle zomhlaba ezifana nokudilika kwenhlabathi, ukudilika kodaka, nokuwa kwemithambeka.Bazobeka usongo oluqondile noma olungase lube usongo ezakhiweni.Lapho kwakhiwa izakhiwo ezisekelweni zezintaba, ukunakwa okukhethekile kufanele kukhokhwe ezicini zendawo ezungezile kanye nezimo ezimbi ze-geological, futhi isisekelo kufanele siphathwe lapho kudingekile.
9. I-Karst Ezindaweni ze-karst, kuvame ukuba nemigede noma imigede yomhlaba, ama-karst gullies, ama-karst crevices, ama-depression, njll. Akhiwa futhi athuthukiswe ukuguguleka noma ukumbozeka kwamanzi angaphansi komhlaba.Banomthelela omkhulu ezakhiweni futhi bathambekele ekuguquguqukeni okungalingani, ukuwa kanye nokuncipha kwesisekelo.Ngakho-ke, ukwelashwa okudingekile kufanele kwenziwe ngaphambi kokwakha izakhiwo.
