1. Indlela yokufumanisa ubunzima obuphantsi
Indlela yokufumanisa ubunzima obuphantsi isebenzisa isando esincinci ukubetha umphezulu wengqumba, kwaye ifumana imiqondiso yamaza oxinzelelo ukusuka kwingqumba ngokusebenzisa izinzwa ezibotshelelwe kumphezulu wengqumba. Impendulo eguquguqukayo yenkqubo yemfumba-yomhlaba iphononongwa kusetyenziswa ithiyori yoxinzelelo lwamaza, kwaye isantya esilinganisiweyo kunye neempawu zokuphindaphinda ziyaguqulwa kwaye zihlalutywe ukuze kufumaneke ingqibelelo yemfumba.
Ubungakanani besicelo: (1) Indlela yokufumanisa ubunzima obuphantsi ifanelekile ekumiseleni ingqibelelo yeemfumba zekhonkrithi, njengeemfumba ezifakwe kwindawo, iipali ezenziwe ngaphambili, i-prestressed pipe piles, i-cement fly ash ash piles, njl.
(2) Kwinkqubo yovavanyo loxinzelelo oluphantsi, ngenxa yezinto ezinjengokunganyangeki komhlaba kwicala lemfumba, ukuthomalaliswa kwempahla yemfumba, kunye notshintsho kwi-impedance yecandelo lemfumba, ukukwazi kunye nokuphakama kwemfumba. Inkqubo yokwandisa amaza oxinzelelo iya kubola ngokuthe ngcembe. Ngokuqhelekileyo, amandla e-stress wave abola ngokupheleleyo ngaphambi kokuba afikelele emazantsi emfumba, okubangela ukungakwazi ukubona umqondiso wokubonisa ezantsi kwemfumba kunye nokumisela ingqibelelo yemfumba yonke. Ngokwawona mava ovavanyo, kulunge ngakumbi ukucutha ubude bengqumba enokulinganiswa bube ngaphakathi kwe-50m kunye nobubanzi besiseko semfumba bube ngaphakathi kwe-1.8m.
2. Indlela yokufumanisa ubunzima obuphezulu
Indlela yokufumanisa ubunzima obuphezulu yindlela yokufumanisa ingqibelelo yesiseko semfumba kunye nomthamo wokuthwala othe nkqo wemfumba enye. Le ndlela isebenzisa ihamile enzima enobunzima obungaphezulu kwe-10% yobunzima bengqumba okanye ngaphezulu kwe-1% yomthamo wokuthwala othe nkqo wengqumba enye ukuwela ngokukhululekileyo kwaye ubethe phezulu kwingqumba ukufumana i-coefficients eguqukayo efanelekileyo. Inkqubo emiselweyo isetyenziselwa ukuhlalutya kunye nokubala ukufumana iiparitha zengqibelelo yesiseko semfumba kunye nomthamo wokuthwala ngokuthe nkqo wemfumba enye. Ikwabizwa ngokuba yiCase method okanye indlela yeCap wave.
Ububanzi besicelo: Indlela yokuvavanya ubunzima obuphezulu ifanelekile kwiziseko zemfumba ezifuna ukuvavanya ingqibelelo yomzimba wemfumba kunye nokuqinisekisa ukuthwala umthamo wesiseko semfumba.
3. Indlela yokuhanjiswa kweAcoustic
Indlela yokungena kwamaza omsindo kukubethelela iityhubhu ezininzi zokulinganisa isandi ngaphakathi kwemfumba ngaphambi kokugalela ikhonkrithi kwisiseko semfumba, esebenza njengeendlela zokuhambisa ipulse ye-ultrasonic kunye neprobes yolwamkelo. Iiparamitha zesandi se-ultrasonic pulse edlula kwicandelo ngalinye elinqamlezayo lilinganiswa inqaku ngenqaku ecaleni kwe-axis longitudinal yemfumba usebenzisa i-ultrasonic detector. Ke, iindlela ezahlukeneyo zamanani okanye izigwebo ezibonwayo zisetyenziselwa ukusetyenzwa kwale milinganiselo, kwaye iziphene zomzimba wemfumba kunye nezikhundla zazo zinikwa ukuchonga udidi lwemfezeko lomzimba wemfumba.
Umda wesicelo: Indlela yokuhanjiswa kwe-acoustic ifanelekile kuvavanyo lwemfezeko yeemfumba zekhonkrithi ezifakwe kwindawo enemibhobho ye-acoustic efakwe ngaphambili, ukugqiba iqondo leziphene zemfumba kunye nokugqiba indawo yazo.
4. Indlela yokuvavanya umthwalo omileyo
Indlela yokuvavanya isiseko sengqumba esisigxina ibhekisa ekusebenziseni umthwalo phezulu kwengqumba ukuqonda intsebenziswano phakathi kwengqumba nomhlaba ngexesha lenkqubo yokufakwa komthwalo. Ekugqibeleni, umgangatho wokwakhiwa kwemfumba kunye nomthamo wokuthwala wemfumba unqunywe ngokulinganisa iimpawu ze-QS curve (okt i-curve settlement).
Ububanzi besicelo: (1) Indlela yokuvavanya umthwalo we-static ifanelekile ukufumanisa umthamo wokuthwala ucinezelo oluthe nkqo lwemfumba enye.
(2) Indlela yokuvavanya umthwalo we-static ingasetyenziselwa ukulayisha imfumba ide ihluleke, inikezela ngedatha enye ye-data umthamo njengesiseko soyilo.
5. Indlela yokugaya kunye ne-coring
Indlela yokomba engundoqo isebenzisa ikakhulu umatshini wokugrumba (udla ngokuba nobubanzi bangaphakathi obuyi-10mm) ukukhupha iisampulu ezingundoqo kwiziseko zemfumba. Ngokusekelwe kwiisampulu ezingundoqo ezikhutshiweyo, izigwebo ezicacileyo zinokwenziwa kubude besiseko semfumba, amandla ekhonkrithi, ubukhulu bentlenga ezantsi kwemfumba, kunye nemeko yomaleko wokuthwala.
Umda wesicelo: Le ndlela ilungele ukulinganisa ubude beemfumba ezifakwe kwindawo, amandla ekhonkrithi kwingqumba yomzimba, ubukhulu bentlenga ezantsi kwemfumba, ukugweba okanye ukuchonga ilitye nomhlaba ukuthwala umaleko ekupheleni kwemfumba, kunye nokumisela udidi lwemfezeko lomzimba wemfumba.
6. Imfumba enye yovavanyo lomthwalo ome nkqo nkqo
Indlela yovavanyo yokumisela i-anti ehambelanayo yokutsalwa kwesakhono semfumba enye kukusebenzisa amandla athe nkqo achasene nokutsalwa inyathelo ngenyathelo kumphezulu wengqumba kwaye ujonge ukufuduswa kokuchasene nokutsalwa komphezulu wemfumba ngokuhamba kwexesha.
Ubungakanani besicelo: Gqiba elona nqanaba lithe nkqo lokuthwala umthamo wengqumba enye; Qinisekisa ukuba umthamo othe nkqo we-tensile uyahlangabezana neemfuno zoyilo; Ukulinganisa ukuxhathisa okusecaleni kwemfumba ngokuchasene nokutsalwa ngaphandle ngoxinzelelo kunye novavanyo lokufuduswa kwengqumba yomzimba.
7. Imfumba enye yovavanyo oluthe tyaba olumileyo lomthwalo
Indlela yokumisela umthamo wokuthwala othe tye wemfumba enye kunye ne-coefficient yokumelana ethe tyaba yomhlaba wesiseko okanye uvavanyo kunye nokuvavanya umthamo othe tyaba wokuthwala imfumba yobunjineli kusetyenziswa iimeko zokusebenza zangempela kufutshane neemfumba ezithe tye. Ingqumba enye yovavanyo lomthwalo othe tye kufuneka yamkele unidirectional yokulayisha imijikelo emininzi kunye nendlela yokuvavanya. Xa ulinganisa uxinzelelo okanye ubunzima bomzimba wemfumba, indlela yomthwalo wolondolozo olucothayo kufuneka isetyenziswe.
Ubungakanani besicelo: Le ndlela ifanelekile ekumiseleni umthamo othe tyaba obalulekileyo kunye nowokugqibela wokuthwala wemfumba enye, kunye nokuqikelela imilinganiselo yokumelana nomhlaba; Qinisekisa ukuba umthamo wokuthwala othe tye okanye ukufuduswa okuthe tye kuyahlangabezana neemfuno zoyilo; Ukulinganisa ixesha lokugoba lomzimba wemfumba ngoxinzelelo kunye novavanyo lokufuduswa.
