Enhancing Usability of the Multi-channel Analysis of Surface Wave (MASW) Technique for Subsurface Physical Property Mapping by Incorporating Random-Array Seismic Acquisition

摘要: Subsurface imaging is very critical to exploit subsurface resources, monitor the fluid movement in reservoir, mapping tunnels etc. As science advances scientists and other researchers are constantly trying develop new techniques methods for that more effective, efficient, robust under varying field conditions. The main focus of this research one such effort improve increase usability Multi-channel Analysis Surface Wave method (MASW) determining regolith rock properties by introducing a type receiver arrangement extend its usage places inaccessible example, near embankments, military places, clandestine burials, Advances near-surface geophysical techniques, as multi-channel analysis surface waves (MASW), have greatly increased our ability map variations physical here on Earth. MASW involves deployment multiple seismometers acquire 1-D or 2-D shear wave velocity profiles can be directly related various engineering properties. purpose presented demonstrate usefulness capabilities technique using random array 1) through controlled site experiments, 2) Modeling 3) And finally apply at terrestrial (the Black Point Lava Flow) with different geologic setting. results studies interpretation geology geophone array. methodologies discussed dissertation, although applicable Earth, also intended surfaces future exploration planetary bodies possible human habitation. This would include Mars, Moon-Phobus/Deimos, Near-Earth Asteroids (NEA’s), even Earth’s Moon. With each situation, nature formational processes will place certain restrictions limitations upon applications. expected any change terrains let alone between bodies.
