Guided waves in near-surface seismic surveys - ResearchGate
WebDec 7, 2011 · At present practically three types of seismic sensors are used: geophones, piezoelectric acceleration sensors, micro-mechanical silicone acceleration sensors. … WebFeb 13, 2024 · The input seismic waves used in the finite element model were the same as the shaking table test. Real properties of the materials of the model had been taken into account. The finite element mode contained 78899 nodes, beam elements 4599, and shell elements 72414 totally.

WebThe propagation speed, or acoustic velocity, of acoustic waves is a function of the medium of propagation. In general, the acoustic velocity c is given by the Newton-Laplace equation: where. C is a coefficient of stiffness, the bulk modulus (or the modulus of bulk elasticity for gas mediums), ρ {\displaystyle \rho } WebS Waves, known as Secondary Waves, are seismic waves that simply go about in an S shape, form, and is the second wave to arrive during an earthquake. S waves cannot travel … WebApr 1, 1998 · The continuous reflection of seismic energy within this layer gives rise to the observed resonant character of the waves, known as guided waves (Roth et al., 1998).
