SUMMARY
Determining
trans-horizontal velocity Vs and elastic parameters of rock and soil
by Multichannel Surface Wave method
Nguyễn Nhật Kim Ngân, Nguyễn Ngọc Thu, Đinh Quốc Tuấn
The article presents the Multichannel Analysis of Surface Wave method
(MASW), is one of the the non-destructive geophysical methods, which does not
require the boreholes in survey, to determine shear velocity Vs and the elastic
parameters in surveying the work foundation. The result is presented in ID
profile showing the change in shear velocity Vs following depth in MASW method.
The results of MASW are conformable to petrographic component on borehole in
the survey. Mean absolute error of Vs following every meter (depth) between
MASW and down-hole is approximately 15.5%.
