This report provides a simplified method to be used for evaluating the skin friction and tip resistance of axially loaded drilled shafts. A summary of literature and current practice was completed and then a comprehensive set of field and laboratory tests was performed. Several soil samples were collected from different sites from Arizona and surrounding states. Large scale direct shear apparatus was developed and used to determine the friction between soil and concrete. Finite element analyses were conducted on several prototype cases to determine effect of soil parameters such as dilation on the skin friction values. A step-by-step simplified approach was introduced to determine the skin and tip resistance of drilled shaft foundations in gravelly soils. An example application was presented to guide users in utilizing the simplified approach.
This report provides an introduction to a method used by anthropologist and archaeologists called the "cultural landscape approach." It reviews the cultural landscapes of the historic and prehistoric periods of southern Arizona and explains the theory of this approach.
This report describes the different, and sometimes conflicting, conceptions of land use that have been held by residents of southern Arizona during the past 500 years. Briefly outlining major events in the Native American, Hispanic, and Anglo experience, the report provides a chronology of events.
This contains two reports. The first is by authors from Statistical Research, Inc. that provides background information on the definition and application of the traditional cultural places designation under the National Historic Preservation Act. The second report is from the National Forest Service and expands on the first with examples of how traditional cultural places can be considered as part of land management planning.
