Determination of Rock Mass Modulus Using the Plate Loading Method in Ambient andThermally Perturbed Environments at Yucca Mountain, Nevada

摘要

The welded tuffs of Yucca Mountain are being considered by the United StatesDepartment of Energy (DOE) as potential host media for the storage of high level waste (HLW). As part of the Site Characterization efforts for the Yucca Mountain Project (YMP), a mechanically excavated Exploratory Studies Facility (ESF) was completed in 1997. A Thermal Testing Facility (TTF), subsequently constructed off the main drift of the ESF, includes the Single Heater Test block and the Drift Scale Test (DST).
