APPLICATION OF RAYLEIGH WAVE DETECTION TECHNOLOGY IN THE FOUNDATION OF DYNAMIC COMPACTION
Xiao Xian-bo · Low Temperature Architecture Technology · 2010
Field tests before and after dynamic compaction of the dredger filled sand dynamic compaction foundation at Xiamen bay were conducted by Rayleigh wave detection technology,and the test results were compared with the dynamic cone penetration test results.Results show that the field layered shear wave velocity is obtained in Rayleigh Wave test,soil mechanics parameters are related to shear wave velocity;Rayleigh wave speed has a certain relevance to foundation bearing capacity which can roughly estimates bearing capacity of the dynamic compaction foundation;test results by Rayleigh wave detection method before and after dynamic compaction are in line with that by the dynamic penetration method,which shows that Rayleigh wave can be effectively applied in the detection of foundation dynamic compaction effect.Some reasonable advices on effectiveness evaluation of the dynamic compaction foundation by Rayleigh wave detection technology were proposed in this paper.
