Abstract: Effective design and construction in rock requires characterization of the engineering properties of the rock mass, as well as any associated geological features such as joints, faults, and bedding planes. Surface geophysics methods (e.g., seismic refraction or reflection) are commonly used to locate buried rock layers, determine depth, and help uncover some information about their properties. However, these surface geophysical techniques often do not provide sufficient engineering information to conduct design analyses, particularly when the designed geo-structural feature (e.g., tunnel or underground utilities) is primarily located inside the rock layers.
