Soil/Terrain Evaluation of Representative Test Areas, Hunter-Liggett Military Reservation, California.
Abstract
Hunter-Liggett Military Reservation was visited to conduct a soil/terrain evaluation of selected areas and to compare the soil strength data collected at the time of visit with the other 155mm XM718/741 Remote Anti-Armor Mine System (RAAMS) test areas previously characterized. Soil/terrain data were collected at eight sites located in the valley used in TEMAWS experiments. The sites sampled included a range of soil types in undulating to rolling terrain. Most sites were covered with short grasses and broad-leaf plants. All sites sampled were very firm at time of testing. The surface cone index ranged from 137 to 563+, and at 2 in. the cone index exceeded the capacity of the instrument (750+). The number of blows necessary to drive the dynamic cone penetrometer 0 to 3 in. ranged from 7 to 30, and for the surface foot ranged from 67 to 120. For the range of soil strength measured, the mines will not penetrate the target and will bounce after impacting the ground. It is estimated from previous penetration analysis for RAAMS that the magnitude of the rigid body g forces that the RAAM can experience upon impacting such firm soils at 200 ft/sec would range from 5000 to 9000 g's.
