RADIOGRAPHIC INSTRUMENTATION STUDY. Final Report
Various radiographic techniques are examined and evaluated to determine their feasibility for the study of dynamic soil phenomena. The data, which could be obtained radiographically, are measurements of particle motion and density change as a function of position and time within the soil. The primary advantage of a radiographic system is that the condition of the soil is not modified by transducers within the soil, except for small pellets that have no measurable influence on the dynamic phenomena. Two specific radiographic systems are examined in great detail. They are used to observe dynamic phenomena in soil samples subjected to suddenly applied loads. One of these systems uses a steady source of x rays, and the other system uses a flash x-ray machine. The radiographic records from these tests are pre sented and analyzed. (auth)
