Quarterly geotechnical field data report

OSTI ID:6409175

The Quarterly Geotechnical Field Data report (GFDR) presents information obtained from the geotechnical studies at the WIPP site from September 15 through December 15, 1983, as well as all previous data collected from the geomechanical instruments. During this period, the geotechnical activities at the site to be reported were primarily concerned with monitoring the geomechanical instruments which have been installed in the exploratory shaft and the underground drifts. Two sets of drift closure points, replacements for those lost when the EO drift floor was lowered, and one floor point at the E 140-S400 intersection, are the only new instruments added this period. The data presented in the GFDR reflect continuing measurements and monitoring. Presented for the first time in this report are preliminary data analyses. These data evaluations and analyses, which are ongoing, will also be reported in future quarterly reports. It is DOE's intent to provide all geotechnical and related information generated from WIPP underground activities to interested persons or groups in a timely manner. The Quarterly GFDR is organized into two major sections. The first, Geotechnical Field Data, contains all the data collected since April 1982 from the geomechanical instrumentation which have been installed in the exploratory shaft and underground drifts at the WIPP site. The second, Evaluation and Analysis, presents preliminary data analyses. Future reports will include a preliminary computational analysis of an underground opening at a selected location in the WIPP underground facility. For this report, a preliminary analysis of a cross section taken in the south exploratory drift is presented. Also included is an evaluation and analysis of the instrumentation measurements and a description of the observed behavior of the underground openings.
