SUBTERRANEAN GUIDEWAY RESPONSES TO LEVITATION VEHICLE LOADING

Tracked air cushion vehicles (TACV's) and magnetic levitation vehicles with speeds up to 300 mph are currently being developed by the U.S. Department of Transportation. The guideways for these levitation vehicles will consist of both above and below ground portions. In this study, the stresses induced by a typical TACV on alternative underground guideway and support systems are analyzed. The effects of the following system parameters on a concrete tunnel liner and the response of the surrounding medium were calculated: the type of guideway base support (solid and strut); the stiffness of the surrounding medium (varying from a soft clay to a moderately hard rock) the load distribution (levitation and/or lateral loading); and the liner thickness. Results show that concrete liners can support the dynamic loads of typical levitation vehicles.
