A METHOD TO REMOTELY MEASURE MICROTREMORS FOR VIBRATION DIAGNOSES OF RAILWAY STRUCTURES
LDV remote measurement microtremor vibration diagnosis railway viaduct
2008/12/22
An accurate method for remotely measuring structure microtremors is proposed by using an improved Laser Doppler Velocimeter (LDV). The remote microtremor measurements of a rigid-frame structure model...
A METHOD TO ESTIMATE PHASE VELOCITIES OF SURFACE WAVES USING ARRAY OBSERVATION RECORDS OF THREE-COMPONENT MICROTREMORS
spatial auto-correlation method phase velocity Rayleigh wave Love wave microtremors array observation
2008/12/22
We propose a method to estimate phase velocities of the Rayleigh and Love waves using array observation records of three-component microtremors. Previous researchers have provided a method on the bas...
