Abstract : Procedures were developed for estimating gross debris accumulation in various types of urban areas, based on complete structural demolition and uniform distribution of the fragmented materials. Theoretical studies on the fragmentation process were initiated toward quantifying the fragment-size distribution of demolished structural elements. Analytical studies of the blast-wind-induced trajectories of structural fragments were performed. These latter two studies were directed toward providing inputs for estimating rubble contours for individual structures and groups of structures i. e., defining depths of rubble that may be expected to cover shelter entranceways and transportation arteries. Estimating tables were prepared to indicate the capacities of excavating equipment in removing debris. Major problems involved in planning and scheduling debris removal operations and the essential elements of a clearance program are described. Associated problems resulting from radioactive contamination of the rubble are discussed. (Author)
