Seismic Refraction

- May 08, 2019-

Seismic refraction yog txoj cai geophysical tswj los ntawm Snell txoj cai (saib Refraction). Siv hauv thaj chaw ntawm engineering geology, geotechnical engineering thiab kev tshawb nrhiav geophysics, siv seismic seev thiab / los yog geophones, arrays thiab lub zog los ua seismic refraction traversals (kab seismic). Seismic refraction siv qhov laj thawj ntawm geological layers thiab geotechnical units los ntawm seismic tsis rau characterize subsurface geological mob thiab geological qauv.


Cov tswv yim no yog nyob ntawm qhov tseeb tias cov dej ntws tsis sib haum muaj ntau qhov sib txawv ntawm cov av (los yog pob zeb): tsis tas li ntawd, cov vuag tsis muaj zog thaum lawv hla dhau tus ciam ntawm ntau hom (lossis xwm txheej) ntawm av lossis pob zeb. Cov kev no tuaj yeem txiav txim siab txog hom av thiab qhov tob ntawm qhov ciam teb stratigraphic los yog txaj.
