Mashandisirwo eMagnetometry muGeophysics
Pendauluan
Magnetometry ndeimwe yenzira dzinoshandiswa zvakanyanya mukuongorora nekuongorora zviwanikwa zvePasi. Iyi nzira inoshandisa misimboti yekutanga yemagnetism kuyera kusiyana kwesimba remagineti rePasi kunokonzerwa nekupararira kwezvinhu zvine magineti pasi pePasi. Chinyorwa chino chichakurukura mashandisirwo akasiyana-siyana emagnetometry mu geophysics, kusanganisira kutsvaga zvicherwa, kuwanikwa kwezvakacherwa, zvidzidzo zvezvakatipoteredza, uye tsvakiridzo ye geotechnical.
Nheyo dzeMagnetometry
Magnetometry inoshanda papfungwa yekuti matombo akasiyana ane hunhu hwakasiyana hwemagnetization. Mudziyo unoshandiswa kuyera masimba emagineti unonzi magnetometer. Kana magnetometer ikaona kusiyana kwesimba remagineti, data iri rinogona kushandiswa kududzira kuvapo nekupararira kwezvinhu zvemagineti pasi pevhu.
Kutsvaga Zvicherwa
Imwe yenzira huru dzekushandisa magnetometry mu geophysics ndeyekutsvaga zvicherwa. Zvicherwa zvakawanda, kunyanya izvo zvine iron, zvine simba guru remagineti. Nekuyera kusagadzikana kwesimba remagineti, nyanzvi dze geophysicists dzinogona kuona nzvimbo dzinogona kuwanikwa dzekuchera zvicherwa.
Semuenzaniso, magnetometry inogona kushandiswa kuwana simbi iri mukati mematombo. Nekuti simbi ine simba rakasimba remagineti, magnetometer ichaona kusarongeka kwakakura kwesimba remagineti kwakakomberedza simbi. Ruzivo urwu runobva rwaongororwa uye rwarongwa, zvichibvumira vacheri kuti vaone nzvimbo dzakanakisa dzekuchera nekuchera.
Zvakawanikwa pakuchera matongo
Magnetometry yakashandiswawo mukuchera matongo senzira isingakuvadzi yekutsvaga nekugadzira mapu enzvimbo dzakavanzwa dzekuchera matongo pasi pevhu. Kusiyana kwemagineti kunokonzerwa nekuchinja kwemaumbirwo kana kusagadzikana kwesimbi kwakavanzika kunogona kuonekwa uchishandisa magnetometry.
Semuenzaniso, zvasara zvezvivakwa zvezvidhinha zvakatsva kana zvivakwa zvesimbi zviri pasi pevhu zvinogona kuratidza kusagadzikana kwemagineti. Mapoka ekuchera matongo anogona kugadzira kusagadzikana uku nemagnetometer uye obva achera nzvimbo dzinonyanya kufungidzirwa dzezvinhu zvakavanzika kana zvivakwa zvekare.
Zvidzidzo zveZvakatipoteredza
Imwe nzira yekushandisa magnetometry mu geophysics ndeyekudzidza nezvezvakatipoteredza. Inogona kushandiswa kuona nekutarisa tsvina kana marara emaindasitiri akavigwa anogona kunge aine simbi yakawanda uye ane simba remagineti. Kutevera kupararira uye kuwanda kwezvinhu zvine magineti muvhu kunogona kubatsira mukuedza kugadzirisa zvakatipoteredza.
Semuenzaniso, nzvimbo yaimbova maindasitiri ingave yakasiya simbi inogona kurongwa uchishandisa magnetometry. Ruzivo urwu runobatsira vanochengetedza nharaunda kusarudza nzvimbo dzakakosha dzekuchenesa kuti ive nechokwadi chekuti ivhu harina kusvibiswa uye rinogona kushandiswazve zvakachengeteka.
Tsvagiridzo yeGeotechnical
Magnetometry inoitawo basa rakakosha mukutsvagisa kwezve geotechnical uye engineering. Nzira iyi inogona kushandiswa kuona zvinhu zviri pasi pevhu zvakaita sezvikanganiso, majoini, kana shanduko mumatombo zvinogona kukanganisa kuvakwa nekugadzikana kwezvivakwa.
Semuenzaniso, pakuronga mugwagwa wepasi pevhu kana mugero, kunzwisisa hunhu hwepasi pevhu kwakakosha. Magnetometry inogona kuratidza ruzivo nezvehunhu hwedombo uye hwemakanika hunofanira kunyudzwa, kuona nzvimbo dzinogona kuva nenjodzi, uye kubatsira mainjiniya kugadzira mapurani akachengeteka uye anoshanda zvakanyanya.
Nzira uye Tekinoroji
Kune mhando dzakasiyana-siyana dzemamagnetometer dzinoshandiswa mukuongorora kwenzvimbo, kusanganisira mamagnetometer escalar, anoyera simba remagineti rose, uye mamagnetometer evector, anoyera zvikamu zvesimba remagineti munzira nhatu. Sarudzo yerudzi rwemagnetometer inoenderana nezvinangwa chaizvo nemamiriro ekuongorora.
Tekinoroji yemazuva ano yakagonesa kushandiswa pamwe chete kwedata remaginetometric pamwe chete nehurongwa hweruzivo rwenzvimbo (GIS) uye nzira dzekugadzirisa data dzedhijitari. Kufambira mberi uku kunopa mhinduro yepamusoro uye kududzira data kwakarurama, zvichibvumira nyanzvi dzenzvimbo kugadzira mamepu enzvimbo ane ruzivo rwakadzama.
Studi Kasus
1. Kuongorora muAustralia: Magnetometry yakashandiswa zvakanyanya mukutsvaga zvicherwa munzvimbo dziri kure dzakadai seAustralia. Zvidzidzo zvemagineti muPilbara neYilgarn Cratons zvakaratidza huwandu hwakawanda hwesimbi, zvichiita kuti makambani emigodhi atangezve kuongorora izvo zvakakonzera kuzivikanwa kwezvicherwa zvekutengeserana.
2. Tsvagiridzo yezvekuchera matongo muIjipita: MuIjipita, magnetometry yakashandiswa kuwana zvivakwa zvepasi pevhu zvisingazivikanwe zvakatenderedza maPiramidhi eGiza. Masayendisiti akawana kusagadzikana kwemagineti kwakaita kuti pawanikwe nzira dzemvura dzepasi pevhu dzaimbofungidzirwa kuti ingano.
Mhedziso
Magnetometry chishandiso chinoshanda zvikuru uye chinoshandiswa zvakasiyana-siyana mu geophysics, chine mashandisirwo akasiyana-siyana kubva pakutsvaga zvicherwa nekuchera matongo kusvika kuzvidzidzo zvezvakatipoteredza nekutsvaga geotechnical. Nekufambira mberi kwetekinoroji, kururama uye kugadziriswa kwedata rinogadzirwa kuri kuramba kuchivandudzwa, zvichipa ruzivo rwakadzama pamusoro pemaumbirwo epasi.
Kuburikidza nekushandisa magnetometry, tinogona kuwana mufananidzo wakajeka uye wakadzama wezviwanikwa zvinogona kuwanikwa uye zviitiko zve geological zvakavanzwa pasi pevhu. Nokudaro, magnetometry icharamba iri chikamu chakakosha chezvishandiso zve geophysicist, ichiramba ichitibatsira kuongorora nekunzwisisa mashandiro akaomarara ePasi.
