Product Description
Crosshole Seismic Equipment Portable Shear Wave Velocity Testing Hammer Downhole Shear Wave Source
The cross-hole shear wave excitation hammer is an intelligent source device designed for accurate measurement of shear wave velocity (Vs) in geotechnical engineering. Based on the principle of air pressure anchor-weight hammer excitation coupling, it realizes directional excitation and synchronous acquisition of formation shear wave signals. It provides high signal-to-noise ratio source guarantee for foundation dynamic parameter evaluation, earthquake safety assessment and underground structure detection.
1. Earthquake engineering, site classification, liquefaction identification
2. Civil engineering: Roadbed modulus detection: obtain the shear wave velocity of roadbed fill, invert the dynamic shear modulus (Gmax)
Tunnel surrounding rock classification: identify the fault fracture zone and rock mass integrity coefficient (Kv) through wave velocity mutation.
3. Environmental geology
Landslide monitoring: regularly test the wave velocity change of sliding zone soil and evaluate the shear strength attenuation in the creep stage;
Frozen soil survey: establish the wave velocity-ground temperature relationship curve and delineate the range of permafrost degradation.
