dc.descriptionAbstract: Results of a field investigation at a proposed DNA full-scale rock penetration site near Los Lunas, New Mexico, and of classification, composition, and mechanical property tests on rock from the site are presented. The mechanical property tests were conducted on material from the upper 3 metres of the site, where the rock is a fine- to medium-grain, red, arkosic sandstone member of the Yeso Formation. This site was intended to be the very-low-strength member of a set of three test sites in medium-, low-, and very-low-strength rock. As a result of the strength data from the laboratory test program, however, it became apparent that the overall program objectives would not be achieved with the Los Lunas site, since (1.) the near-surface strength is intermediate between those at two sites already used for fullscale penetration tests, and (2.) a layer interface exists (below which lies an even higher strength rock) at the site within the depth range which would be exercised in a penetration test (3 to 5 metres). Consequently, it was recommended to DNA that the remaining full-scale penetration test not be conducted at the Los Lunas site.-
