COMBINATION PROBE - A NEW INSTRUMENT FOR SUBSURFACE EXPLORATION

As part of its highway transportation research program, the Federal Highway Administration (FHWA) has investigated tunneling technology extensively to reduce the engineering risks, and therefore the costs, associated with highway tunnel construction. Experience has shown that attempts to reduce engineering costs by minimizing investigation of a proposed tunnel site often are counterproductive. Misjudging underground structure may result in selecting the wrong tunnel excavation technique or under- or overdesigning the tunnel supports. Present methods for obtaining pertinent information for the design and construction of a highway tunnel include assembling geophysical and geotechnical information from other nearby projects. The combination probe system promises to be a powerful tool for reducing tunnel constructions costs by interpreting the geophysical data of the given tunnel site.
