Na~i~an, M ~; E ~ i ~ , c L Geophysics, V41, EbA, Dec 1976, P1236-1255 772169 USE OF GEOPHYSICS IN LANDSLIDE STUDIES Stewart, M; Cells C, A Transport and Road Research Lab, lab report 703, 1976, 20P Reports a study of geophysical methods of site investigation, used in Colombia, to determine their effectiveness in obtaining sub-surface i~formstion. The techniques included seismic refraction and electrical resistivity, amd the sites selected were e~amples of different classes of landslide. Seismic refraction surveys showed good correlation with borehole information, and the rock, boulder ar~ clay layers reported in the borehole logs ccrrespomded to the different velocity lawyers indicated. Electrical resistivity soumdi21gs were affected by the moisture eorzlltions, amd where weathered layers exist within bemds of rock they adversely affect the results obtained.
mar~ illustrative examples amd solved illustrat problems in customary ar~ SI units. 772171 MATRIX ~THODS OF STRUCTURAL ANALYSIS Livesley, R K Oxford: PergemonPress, 1975, 277P This textbook includes the followirg chapters: main variables amd relationships, elastic properties of sirgle elements, equilibril~n or displacement method, equilibrium equations of a complete structure, plastic analysis and design compatibility or force method, transfer matrice~ ar~lysis Of non-linear structures, problems of size amd accuracy, ~ of the main equation.. and apperzLix: vectors and matrices. 772172 SHOCK PROPAGATION IN SOLIDS Hsrdi~g, J Sci Frog, V63, N252, 1976, P575-603 The propagation of one-dimensional plane-stress waves of .msll amplitude, where %hermod~rmmic effects may be ignored, is first discussed. The ~ t h o d of characteristics is develope~ and brief illustrated by the propagation of unloadlrg sheckfronts. Strain rate effects in the equatioz of state are then discussed and Maivern's analys is outlined. The propagation of one-dimenslo~al plane-strain waves of large amplitt~ie, where thermody~sm~c effects become important, is discussed amd the h y ~ m ~ e theory for the propegation of large amplitude shocks is developed.
