1. Indlela yokuthola ubunzima obuphansi
Indlela yokuthola uhlobo oluphansi isebenzisa isando esincane ukuze ishaye inqwaba, futhi ithola amaza okucindezeleka enqwabeni ngezinzwa eziboshelwe phezulu. Ukusabela okuguquguqukayo kwesistimu yenqwaba-yenhlabathi kufundwa kusetshenziswa ithiyori yegagasi lokucindezeleka, futhi isivinini esilinganiselwe kanye namasignali amafrikhwensi aguqulwa futhi ahlaziywe ukuze kutholwe ubuqotho benqwaba.
Ububanzi bokusebenza: (1) Indlela yokuthola uhlobo oluphansi ifanele ukunquma ubuqotho bezinqwaba zikakhonkolo, njengezinqwaba eziphonswe endaweni, izinqwaba ezenziwe ngaphambilini, izinqwaba zamapayipi agxilile, izinqwaba zomlotha we-cement fly, njll.
(2) Enqubweni yokuhlolwa kobunzima obuphansi, ngenxa yezinto ezinjengokumelana nokungqubuzana kwenhlabathi ohlangothini lwenqwaba, ukucwiliswa kwempahla yenqwaba, kanye noshintsho ekubambeni kwengxenye yenqwaba, ikhono kanye nokuphakama kwenqwaba. inqubo yokusabalalisa igagasi lokucindezeleka izobola kancane kancane. Ngokuvamile, amandla egagasi lokucindezeleka abole ngokuphelele ngaphambi kokuba afinyelele phansi kwenqwaba, okuholela ekungakwazini ukubona isignali yokubonisa ngaphansi kwenqwaba futhi inqume ubuqotho bayo yonke inqwaba. Ngokolwazi lwangempela lokuhlola, kufanelekile kakhulu ukukhawulela ubude benqwaba elinganisekayo bube phakathi kwama-50m kanye nobubanzi besisekelo senqwaba bube phakathi kuka-1.8m.
2. Indlela yokuthola ubunzima obuphezulu
Indlela yokuthola ubunzima obuphezulu iyindlela yokuthola ubuqotho besisekelo senqwaba kanye namandla okuthwala aqondile wenqwaba eyodwa. Le ndlela isebenzisa isando esindayo esinesisindo esingaphezu kuka-10% wesisindo senqwaba noma ngaphezulu kwe-1% yomthamo wokuthwala oqondile wenqwaba eyodwa ukuze iwe ngokukhululeka futhi ishaye phezulu kwenqwaba ukuze kutholwe ama-coefficient ashukumisayo afanele. Uhlelo olunqunyiwe lusetshenziselwa ukuhlaziywa nokubala ukuze kutholwe imingcele yobuqotho yesisekelo senqwaba kanye namandla okuthwala aqondile wenqwaba eyodwa. Yaziwa nangokuthi indlela ye-Case noma indlela ye-Cap wave.
Ububanzi bokufaka isicelo: Indlela yokuhlola ubunzima obuphezulu ifanele izisekelo zenqwaba ezidinga ukuhlola ubuqotho bomzimba wenqwaba kanye nokuqinisekisa umthamo wokuthwala wesisekelo senqwaba.
3. Indlela yokudlulisa i-Acoustic
Indlela yokungena kwamagagasi omsindo iwukushumeka amashubhu okulinganisa umsindo amaningana ngaphakathi kwenqwaba ngaphambi kokuthela ukhonkolo kusisekelo senqwaba, esebenza njengemigudu yokudlulisa ishayela nge-ultrasonic kanye nama-probe okwamukela. Imingcele yomsindo we-ultrasonic pulse edlula esigabeni ngasinye esiphambanayo ikalwa iphuzu nephuzu eduze kwe-axis longitudinal yenqwaba kusetshenziswa umtshina we-ultrasonic. Khona-ke, imibandela yezinombolo ethile ethile noma ukwahlulela okubukwayo kusetshenziswa ukucubungula lezi zilinganiso, futhi amaphutha omzimba wenqwaba kanye nezikhundla zawo kunikezwa ukuze kunqunywe isigaba sobuqotho somzimba wenqwaba.
Ububanzi bokusebenza: Indlela yokudlulisa i-acoustic ifanele ukuhlolwa kobuqotho kwezinqwaba zikakhonkolo ezifakwe endaweni enamashubhu ashumekiwe acoustic, okunquma izinga lokukhubazeka kwenqwaba kanye nokunquma indawo yazo.
4. Indlela yokuhlola umthwalo omile
Indlela yokuhlola i-pile foundation static load ibhekisela ekusebenziseni umthwalo phezulu kwenqwaba ukuze kuqondwe ukusebenzisana phakathi kwenqwaba nenhlabathi ngesikhathi senqubo yokufaka isicelo. Ekugcineni, ikhwalithi yokwakha yenqwaba kanye namandla okuthwala inqwaba kunqunywa ngokulinganisa izici zejika le-QS (okungukuthi ijika lokuhlala).
Ububanzi bokusebenza: (1) Indlela yokuhlola umthwalo omile ifanele ukuthola umthamo wokuthwala okucindezelayo ome mpo wenqwaba eyodwa.
(2) Indlela yokuhlola umthwalo omile ingasetshenziswa ukulayisha inqwaba ize ihluleke, inikeze idatha yomthamo wokuthwala inqwaba njengesisekelo sokuklama.
5. Indlela yokubhoboza nokufaka amakhora
Indlela yokumba eyingqikithi isebenzisa umshini wokumba (ngokuvamile onobubanzi obungaphakathi obuyi-10mm) ukuze kukhishwe amasampula angumongo ezisekelweni zenqwaba. Ngokusekelwe kumasampula ayinhloko akhishiwe, izinqumo ezicacile zingenziwa ngobude besisekelo senqwaba, amandla okhonkolo, ukushuba kwenhlabathi phansi kwenqwaba, kanye nesimo sengqimba yokuthwala.
Ububanzi bokusebenza: Le ndlela ifaneleka ukulinganisa ubude bezinqwaba ezifakwe endaweni, amandla kakhonkolo emzimbeni wenqwaba, ubukhulu benhlabathi ngaphansi kwenqwaba, ukwahlulela noma ukuhlonza izakhiwo zedwala nenhlabathi yenqwaba. okuthwala ungqimba ekugcineni kwenqwaba, nokunquma isigaba sobuqotho somzimba wenqwaba.
6. Inqwaba yokuhlolwa komthwalo omile okuqinile okukodwa okukodwa
Indlela yokuhlola yokunquma amandla ahambisanayo ahambisanayo aphikisana nokudonsa kwenqwaba eyodwa ukusebenzisa amandla aqinile wokulwa nokudonsa isinyathelo ngesinyathelo phezulu kwenqwaba futhi ubheke ukugudluzwa okunqanda ukudonsa kwenqwaba ephezulu ngokuhamba kwesikhathi.
Ububanzi bokusebenza: Nquma umthamo wokugcina wokuthwala oqinile wenqwaba eyodwa; Nquma ukuthi umthamo wokuthwala ukuqina oqondile uyahlangabezana yini nezidingo zedizayini; Linganisa ukumelana kwe-lateral kwenqwaba ngokumelene nokukhipha ngokusebenzisa ubunzima nokuhlolwa kokugudluzwa komzimba wenqwaba.
7. Inqwaba yokuhlolwa komthwalo omile ovundlile
Indlela yokunquma umthamo wokuthwala ovundlile wenqwaba eyodwa kanye ne-coefficient yokumelana evundlile yenhlabathi yesisekelo noma ukuhlola nokuhlola umthamo wokuthwala ovundlile wezinqwaba zobunjiniyela usebenzisa izimo zokusebenza zangempela eziseduze nezinqwaba ezithwala imithwalo evundlile. Ukuhlolwa komthwalo ovundlile kwenqwaba eyodwa kufanele kusebenzise indlela yokuhlola yokulayisha nokukhipha imijikelezo eminingi engaqondile. Lapho kulinganiswa ukucindezeleka noma ubunzima bomzimba wenqwaba, indlela yomthwalo wokulungisa kancane kufanele isetshenziswe.
Ububanzi bokusebenza: Le ndlela ifaneleka ekunqumeni umthamo wokuthwala ovundlile nowokugcina wenqwaba eyodwa, nokulinganisa imingcele yokumelana nenhlabathi; Nquma ukuthi umthamo wokuthwala ovundlile noma ukufuduka okuvundlile kuyahlangabezana yini nezidingo zedizayini; Linganisa isikhathi sokugoba somzimba wenqwaba ngokusebenzisa ubunzima nokuhlola ukususwa.
