Isiseko esenziwe ngokuzalisa umhlaba sinokuthathwa njengoluhlobo lwesiseko sendalo. Iimpawu zayo zobunjineli zixhomekeke ikakhulu kwiipropati zomhlaba wokuzalisa. Gcwalisa isiseko somhlaba ngokubanzi sineempawu ezibalulekileyo ezilandelayo. (1) I-particle sedimentation ngokucacileyo ihlelwe. Kufuphi nendawo yokungenisa udaka, amasuntswana arhabaxa afakwa kuqala. Kude kwindawo yokungena yodaka, iincinci ezifakwe kwi-deposit ziba ngcono. Kwangaxeshanye, kukho istratification ecacileyo kwicala lobunzulu. (2) Isiqulatho samanzi somhlaba ogcwalisiweyo siphezulu kakhulu, sikhulu ngokubanzi kunomda wolwelo, kwaye ukwimo equkuqelayo. Emva kokuba ukuzaliswa kumisiwe, umphezulu uhlala uqhekeka emva kokunyuka kwemvelo, kwaye umxholo wamanzi uyancipha kakhulu. Nangona kunjalo, umhlaba ogcweleyo osezantsi usekwimeko equkuqelayo xa iimeko zokuhambisa amanzi zingentle. Ukugqwesa amasuntswana omhlaba azalisekileyo, kokukhona kubonakala ngakumbi le nto. (3) Amandla okuqala esiseko sokuzalisa umhlaba aphantsi kakhulu kwaye ukunyanzeliswa kuphezulu kakhulu. Oku kungenxa yokuba umhlaba wokuzalisa ukwimeko engadityaniswanga. Isiseko sokubuyisela ngokuthe ngcembe sifikelela kwisimo esiqhelekileyo sokudityaniswa njengoko ixesha le-static linyuka. Iimpawu zayo zobunjineli zixhomekeke ekubunjweni kweengqungquthela, ukufana, iimeko zokudibanisa amanzi kunye nexesha elimileyo emva kokubuyisela umva.
4. Intlabathi yentlenga yomhlaba oxutyiweyo okanye isiseko sesanti ecolekileyo sihlala sinamandla aphezulu phantsi komthwalo omileyo. Nangona kunjalo, xa umthwalo we-vibration (inyikima, ukungcangcazela komatshini, njl.njl.) usebenza, isiseko somhlaba onesanti ehlulileyo sinokuthi sinyibilike okanye singene kwisixa esikhulu sogulo lokungcangcazela, okanye lude luphulukane nomthamo walo wokuthwala. Oku kungenxa yokuba amasuntswana omhlaba alungelelaniswe ngokukhululekileyo kwaye indawo yamasuntswana iyasuswa phantsi kwentshukumo yamandla aguquguqukayo angaphandle ukuze kuzuzwe ulungelelwaniso olutsha, oluthi ngoko nangoko luvelise uxinzelelo lwamanzi olungaphezulu kwipore kwaye uxinzelelo olusebenzayo lwehla ngokukhawuleza. Injongo yokuphatha esi siseko kukwenza ukuba kube nzima ngakumbi kwaye kuphelise ukubakho kwe-liquefaction phantsi komthwalo onamandla. Iindlela zonyango eziqhelekileyo ziquka indlela ye-extrusion, indlela ye-vibroflotation, njl.
5. Ilahleko egobileyo Umhlaba owenza i-deformation eyongezelelweyo ebalulekileyo ngenxa yokutshatyalaliswa kwesakhiwo somhlaba emva kokuntywiliselwa phantsi koxinzelelo lwe-self-weight stress of overlying the layer, okanye phantsi kwesenzo esidityanisiweyo sokuxinezeleka kunye noxinzelelo olongezelelweyo, kuthiwa yi-collapsible. umhlaba, ongowomhlaba okhethekileyo. Eminye imihlaba ezaliswe yingxubevange nayo iyaqengqeleka. Ilahleko isasazwe ngokubanzi kuMntla-mpuma welizwe lam, kuMntla-ntshona weTshayina, kuMbindi weTshayina kunye nenxalenye yeMpuma yeTshayina ubukhulu becala buboleka. (Le ntsinjana ikhankanywe apha ibhekisa kumhlaba olahlekileyo nofana nelahleko. Ilahleko eqengqelekayo yahlulahlulwe yaba yilahleko egoqekayo yobunzima bobuqu kunye nelahleko engakwaziyo ukuzilinganisela, kunye nenye ilahleko endala ayiqengqeleki). Xa usenza ulwakhiwo lobunjineli kwiziseko ezilahlekayo, kuyafuneka ukuba kuqwalaselwe ingozi enokwenzeka kwiprojekthi ebangelwa kukuhlaliswa okongeziweyo okubangelwa kukuwa kwesiseko, kwaye ukhethe iindlela ezifanelekileyo zonyango lwesiseko ukuphepha okanye ukuphelisa ukuwa kwesiseko okanye umonakalo obangelwa inani elincinci lokuwa.
6. Umhlaba owandisiweyo Icandelo leminerali yomhlaba obanzi kakhulu yi-montmorillonite, ene-hydrophilicity eyomeleleyo. Iyakwandisa umthamo xa ifunxa amanzi kwaye iyancipha umthamo xa ulahlekelwa ngamanzi. Oku kwandiswa kunye nokuguqulwa kokunciphisa kudla ngokuba kukhulu kakhulu kwaye kunokubangela umonakalo kwizakhiwo. Umhlaba owandisiweyo usasazwa ngokubanzi kwilizwe lam, njengeGuangxi, Yunnan, Henan, Hubei, Sichuan, Shaanxi, Hebei, Anhui, Jiangsu kunye nezinye iindawo, kunye nokuhanjiswa okwahlukeneyo. Umhlaba obanzi luhlobo olulodwa lomhlaba. Iindlela eziqhelekileyo zonyango lwesiseko zibandakanya ukutshintshwa komhlaba, ukuphuculwa komhlaba, ukucwina kwangaphambili, kunye neendlela zobunjineli zokuthintela utshintsho kumxholo wokufuma womhlaba wesiseko.
7. Umhlaba ophilayo kunye ne-peat Xa umhlaba uqulethe izinto eziphilayo ezahlukeneyo, imihlaba eyahlukeneyo yendalo iya kwenziwa. Xa isiqulatho se-organic matter sidlula isiqulatho esithile, umhlaba we-peat uyakwenziwa. Ineempawu zobunjineli ezahlukeneyo. Ukuphakama komxholo we-organic matter, impembelelo enkulu kumgangatho womhlaba, obonakaliswa ngamandla aphantsi kunye noxinzelelo oluphezulu. Kwakhona kuneempembelelo ezahlukeneyo ekufakweni kwezinto ezahlukeneyo zobunjineli, ezinempembelelo embi ekwakheni ubunjineli ngokuthe ngqo okanye unyango lwesiseko.
8. Umhlaba wesiseko sentaba Iimeko zejoloji zomhlaba wesiseko sentaba zintsonkothile, ikakhulu zibonakaliswa ngokungalingani kwesiseko kunye nokuzinza kwesiza. Ngenxa yempembelelo yendalo esingqongileyo kunye neemeko zokubunjwa komhlaba wesiseko, kunokubakho amatye amakhulu kwisiza, kwaye indawo yendawo inokuba neziganeko ezimbi zejoloji ezifana nokudilika komhlaba, ukudilika kodaka, kunye nokuwa kwethambeka. Ziya kubangela ingozi ngokuthe ngqo okanye enokubakho kwizakhiwo. Xa ukwakhiwa kwezakhiwo kwiziseko zeentaba, ingqalelo ekhethekileyo kufuneka ihlawulwe kwiindawo zokusingqongileyo kunye neziganeko ezimbi ze-geological, kwaye isiseko kufuneka siphathwe xa kuyimfuneko.
9. I-Karst Kwiindawo ze-karst, kuhlala kukho imiqolomba okanye imiqolomba yomhlaba, ii-karst gullies, ii-karst crevices, ii-depressions, njl.njl. Zenziwa kwaye ziphuhliswe lukhukuliseko okanye ukuthotywa kwamanzi aphantsi komhlaba. Zinempembelelo enkulu kwizakhiwo kwaye zixhomekeke kwi-deformation engalinganiyo, ukuwa kunye nokuthotywa kwesiseko. Ngoko ke, unyango oluyimfuneko kufuneka lwenziwe ngaphambi kokwakha izakhiwo.
