Branching of Dispersion Curves in Surface Wave Testing of Pavements
When a set of simulated multichannel seismic records acquired over pavement is processed by a 2-D wavefield transformation technique normally used in the Multichannel Analysis of Surface Waves (MASW) method, several branches are observed in the dispersion-curve image constructed from the transformation. Some investigators theoretically anticipated this branching phenomenon a few decades ago in ...
متن کاملNon-contact surface wave measurements on pavements
In this thesis, nondestructive surface wave measurements are presented for characterization of dynamic modulus and layer thickness on different pavements and cement concrete slabs. Air-coupled microphones enable rapid data acquisition without physical contact with the pavement surface. Quality control of asphalt concrete pavements is crucial to verify the specified properties and to prevent pre...
متن کاملNon-contact surface wave testing of pavements using a rolling microphone array
We present experiments where a multichannel array of microphones and an automatic source are attached on a small trolley so that measurements can be taken almost continuously while moving. Measurements on asphalt or concrete pavement layers are based on supersonic leaky air-coupled surface waves. Results show that microphones can be successfully used to measure surface wave dispersion curves ev...
متن کاملNondestructive Dynamic Testing of Soils and Pavements
Non destructive testing techniques based on the application of dynamic loads on the surface of a soil deposit or a pavement system, and the measurement of the resulting deflection basins or the phase difference between the motions recorded at various receivers have become powerful tools in civil engineering. In many cases, however, the interpretation of the recorded data relies on static analys...
متن کاملApplication of artificial neural networks in solving inversion problem of surface wave method on pavements
Surface wave method is an in-situ nondestructive testing procedure for estimation of elastic moduli and layers thicknesses of layered structures such as pavements and natural soil deposits. In this research "Matlab" has been employed for applying artificial neural networks in solving inversion problem of surface wave test dispersion curve and estimating the soil profile. Multi layer neural netw...
