【 摘 要 】

This report describes the 2006 fiscal year field activities associated with the installation of four cable-tool-drilled boreholes located within the boundary of the Waste Treatment Plant (WTP), DOE Hanford site, Washington. The cable-tool-drilled boreholes extend from surface to ~20 ft below the top of basalt and were utilized as cased entry holes for three deep boreholes (approximately 1400 ft) that were drilled to support the acquisition of sub-surface geophysical data, and one deep corehole (1400 ft) that was drilled to acquire continuous core samples from underlying basalt and sedimentary interbeds. The geophysical data acquired from these boreholes will be integrated into a seismic response model that will provide the basis for defining the seismic design criteria for the WTP facilities.
