A methodology and preliminary application for designing repository openings to withstand vibratory ground motions is presented. The methodology first establishes the design basis ground...

Block Dynamics Modeling in Support of Seismic Design
The behavior of an underground excavation is usually characterized by stresses and displacements which develop around the excavation as a result of prevailing field conditions. For conventional...

Seismic Considerations in Sealing a Potential High-Level Radioactive Waste Repository
The potential repository system is intended to isolate high-level radioactive waste at Yucca Mountain according to the performance objective - 10 CFR 60.112. One subsystem that may contribute...

Options for Dynamic Analyses of Underground Facilities
Continuum and discontinuum modeling techniques for conducting dynamic analysis of underground facilities of geologic repository are discussed. Compared with continuum analysis, the discontinuum...

Dynamic Response of Tunnels in Jointed Rocks
We describe the application of the Discrete Element Method (DEM) to the dynamic analysis of the response of tunnels in jointed rocks to earthquake loading. In situations where large motions...

Guidelines for the Development of Natural Phenomena Hazards Design Criteria for Surface Facilities
