Udonga lwenhlabathi yesamente luyindlela yokusekela engeyona ejwayelekile, efanelekela izimo zenhlabathi encane, futhi alusetshenziswa kabanzi ekusetshenzisweni kobunjiniyela obusebenzayo. Izindonga zomhlaba zesamente zivame ukusetshenziswa emigodini yesisekelo senhlabathi ethambile enobunzulu obuncane. Ngaphansi kwalezi zimo, induku yesamente ayinayo ungqimba lomhlabathi olufanele, olungakwazi ukunikeza amandla anele okubamba, futhi ukwesekwa kwangaphakathi kuzokwandisa ubunzima bokwakha isakhiwo esiyinhloko esingaphansi komhlaba. Kuleli qophelo, lapho ukuqhathanisa okuphelele komnotho, isikhathi sokwakha, ukusebenza kobuchwepheshe, njll. kungcono kakhulu, izindonga zomhlabathi zesamente ngokuvamile zikhethwa njengendlela yokusekela. Izindonga zomhlabathi zesamente ngokuvamile zisebenzisa izinqwaba zokuxuba, kanti izinto zodonga ziyinhlabathi yesamente, enamandla amancane okubamba nokusika. Uma zakhiwe ngesakhiwo sensimbi, ukusebenza kwazo kubi futhi azinakuqhathaniswa nezinto zesamente. Ngakho-ke, kuphela uma zakhiwe ngokwesakhiwo esisekelwe ekudonseni amandla lapho zingaba nezinzuzo ezithile.
Uma kusetshenziswa izindonga zokugcina usimende emigodini yesisekelo senhlabathi kanye nenhlabathi, ukujula komgodi akufanele kudlule amamitha angu-7. Ngenxa yomklamo osekelwe ekudonseni amandla, kudingeka ububanzi bodonga obukhulu. Uma ukujula komgodi wesisekelo kungaphezu kwamamitha angu-7, njengoba ukujula komgodi kukhuphuka, ububanzi nokujula kodonga kuba kukhulu kakhulu, okungafaneleki ngokwezomnotho, ngokwezindleko zokwakha kanye nesheduli. Ukujula okunganele kodonga kuzobangela ukufuduka kanye nokuhlangana, kuyilapho ububanzi obunganele buzobangela ukuqhekeka noma ukugumbuqelwa kodonga. Nakuba izindonga zomhlabathi zesamente ezinezinqwaba zokuxuba zingasetshenziswa futhi emigodini yesisekelo ezinhlotsheni zomhlabathi ezifana nomhlabathi ohlangene, inhlabathi, kanye nomhlabathi onesihlabathi, ngokuvamile kungcono ukukhetha ezinye izinhlobo zokusekela. Ezimweni ezikhethekile, izindonga zomhlabathi zesamente ezinezinqwaba zokuxuba zingasetshenziswa kulezi zinhlobo zomhlabathi.
Uma kuqhathaniswa nesakhiwo sokugcina, kusenezinkinga ezithile ezingaxazululwanga noma ukuntuleka kokuqonda okuvuthiwe nokuhlangene ekwakhiweni kwezindonga zezinzipho zenhlabathi. Isibonelo, njengesakhiwo, ayikho indlela ephelele yokuhlaziya isakhiwo yezindonga zezinzipho zenhlabathi, futhi izinkinga zokucindezelwa kwezinzipho zenhlabathi kanye nokucindezeleka kwezingqimba zomhlaba ngaphansi kwezimo zokusebenza azikaxazululwa. Ukwakheka kwezingqimba zomhlaba kungaxazululwa kuphela ngezidingo zesakhiwo. Imithetho efanele ibeka izidingo zokwakhiwa kwezingqimba zomhlaba, kodwa ikhawulelwe emigodini yesisekelo enenhlabathi engathambile futhi engenazo izimo zamanzi angaphansi komhlaba ngaphakathi kokujula okungu-12m. Inkinga yokubala ukufuduka kwezindonga zezinzipho zomhlaba ayixazululwanga ngokuyisisekelo. Ngenxa yomkhuba ovamile wezindonga zezinzipho zomhlaba eShayina, ongasebenzisi i-prestress ezinzipho zomhlaba, izinzipho zomhlaba zizofinyelela kuphela ezingeni lazo lokucindezeleka kokusebenza ngemva kokuguquka okuthile komgodi wesisekelo. Ngakho-ke, ngokombono, ukufuduka kanye nokuhlaliswa kwezindonga zezinzipho zomhlaba kukhulu kakhulu. Uma kunezakhiwo noma ezinye izakhiwo ngaphakathi kobubanzi obuthintekile bokuguqulwa ezungeze umgodi wesisekelo, akufanele ukusebenzisa ukwesekwa kodonga lwezinzipho zomhlaba.
