Abstract:

The studies presented are designed to illustrate, in a broad sense, application of appropriate techniques of excavation to general subsurface conditions which occur in the continental United States. Specific subsurface conditions for open cut excavations and general parameters of conditions for tunnel excavations are established to provide a practicable range of study results. These conditions are analyzed individually, with respect to the type and geometry of the excavation, for evaluation of an effective and economical technique of excavation, and from that evaluation the determination of related cost factors. Summation of these cost factors and further analysis is presented. The results of review of the general field of excavation techniques as pertains to this report are also presented. These include description and evaluation of techniques, utilizing materials and equipment in common and special usage and proved to be of economic value, techniques under development which would be appropriate for consideration, and undeveloped techniques which might be considered promising with respect to excavations contemplated.
