Kwiimeko ezahlukeneyo, ukusetyenziswa kweendlela ezinzulu zokuxuba ukwakhiwa kweenkqubo zokuxhasa ukumba kunye neemveliso zokuxhasa umhlaba zihlala ziyindlela yokuzikhethela ngokusekelwe kwiimfuno zokuyila, iimeko zesayithi / izithintelo kunye noqoqosho.Ezi meko zibandakanya ubukho bezakhiwo ezikufutshane ezinokunyamezela intshukumo encinci yecala;ubukho bentlabathi evulekileyo okanye ehambayo;imfuneko yodonga olufanelekileyo olusikiweyo ukuthintela ukuthotywa kwamanzi aphantsi komhlaba akufuphi kunye nokuhlaliswa kwawo okubangelwa kwezinye izakhiwo;kunye nesidingo sokuxhasa ngaxeshanye isakhiwo esisecaleni, ngelixa kusakhiwa udonga lwenkxaso yokomba.Ezinye iinkqubo ezifana nemiqadi yejoni eliqhelekileyo kunye neendonga ezisikeleyo zinokunika umsebenzi onganelisiyo, ukufakelwa kweengqumba zamaphepha ashukumayo okanye aqhutywayo kunokubangela ukungcangcazela kwezakhiwo ezimeleneyo, ngelixa iindonga zekhonkrithi zediaphragm zidla ixesha kwaye zibiza kakhulu.Ngokusekwe phantsi kweemeko, ukusetyenziswa kwe-multiple-auger okanye i-auger enye indlela yokuxuba nzulu, iindlela ze-jet grouting, okanye indibaniselwano yeendlela ezininzi zinokufuneka.Ukubonisa ukusetyenziswa kokuxuba okunzulu kwiimeko ezahlukeneyo, iimbali ezininzi zeembali zinikezelwe.Kwiiprojekthi eWisconsin nasePennsylvania, indlela yokuxutywa kwe-auger deep yasetyenziswa ngempumelelo ukucutha intshukumo esecaleni yezakhiwo ezikufutshane, ukuthintela ilahleko yenkxaso ngenxa yokuqhawuka kwemihlaba kunye nokulawula amanzi aphantsi komhlaba.
Ulwakhiwo lwemodyuli lubhalwe ukuba luphezulu kuneendlela zokwakha zemveli ngokweshedyuli, umgangatho, uqikelelo, kunye nezinye iinjongo zeprojekthi.Nangona kunjalo, ukunqongophala kokuqonda kunye nolawulo olululo lweemingcipheko zeemodyuli ezizodwa zibhalwe phantsi ukuze zibe nesiphumo sokusebenza okunganeno kwiiprojekthi zokwakha zeemodyuli.Nangona iinzame ezininzi zophando zangaphambili zijolise kwimiqobo kunye nabaqhubi abanxulumene nokwamkelwa kolwakhiwo lweemodyuli kwishishini, akukho msebenzi wophando wangaphambili uye wajongana neengozi eziphambili ezichaphazela iindleko kunye neshedyuli yeeprojekthi zokwakha iimodyuli.Eli phepha lizalisa esi sikhewu solwazi.Ababhali basebenzise indlela yokwenza uphando ngamanyathelo amaninzi.Okokuqala, uphando lwasasazwa kwaye lwaphendulwa ngabasebenzi bezokwakha be-48 ukuba bahlolisise imiphumo ye-50 yengozi yeemodyuli ezichongiweyo ngokusekelwe kuphononongo loncwadi olucwangcisiweyo kwisifundo sangaphambili.Okwesibini, uvavanyo lwe-alpha lweCronbach lwenziwa ukujonga ukuqinisekiswa kophando kunye nokuthembeka.Ekugqibeleni, uhlalutyo lwekhonkodensi ye-Kendall, indlela enye ye-ANOVA, kunye novavanyo lwe-Kruskal-Wallis lwenziwa ukuphonononga imvumelwano yeempendulo ngaphakathi ngalunye kunye naphakathi kwabachaphazelekayo abahlukeneyo kwiiprojekthi zokwakha zeemodyuli.Iziphumo zibonise ukuba ezona zinto zibaluleke kakhulu ezichaphazela iindleko kunye neshedyuli yeeprojekthi zeemodyuli (1) ukunqongophala kwabasebenzi abanezakhono nabanamava, (2) utshintsho loyilo lwasemva kwexesha, (3) iimpawu zesiza ezihlwempuzekileyo kunye nolungiselelo, (4) ukungafaneleki koyilo lwemodyuli. , (5) iingozi zekontraki neengxabano, (6) ukungabikho kwentsebenziswano nolungelelwaniso olwaneleyo, (7) imingeni enxulumene nokunyamezelana kunye nonxibelelwano, kunye (8) nokungacwangciswanga kakuhle komsebenzi wokwakha.Olu phononongo longeza kumzimba wolwazi ngokunceda iingcali ukuba ziqonde ngcono izinto eziphambili zomngcipheko ekufuneka ziqwalaselwe ukunyusa ukusebenza kweeprojekthi zabo zokwakha iimodyuli.Iziphumo zibonelela ngengqiqo yolungelelwaniso lwabachaphazelekayo kwizinto ezahlukeneyo zomngcipheko ezichaphazela iindleko kunye neshedyuli kwiiprojekthi zokwakha zeemodyuli.Oku kufuneka kuncede iingcali ukuba ziseke izicwangciso zokunciphisa ngexesha lamanyathelo okuqala eprojekthi.
