Development of a physical slope failure model.
Dwyer, Todd Douglas.

Development of a physical slope failure model. - 110 p.

Source: Masters Abstracts International, Volume: 43-01, page: 0314.

Thesis (M.S.)--University of Missouri - Columbia, 2004.

The objective of this research has been to develop and "calibrate" a physical slope failure model in the laboratory. The device is eventually to be used to evaluate load transfer in a variety of types of soil reinforcement such as soil nails, soil dowels, and micropiles. The basic principle of the apparatus is to induce failure in a model slope by incrementally increasing the slope inclination to the point of failure. The scope of the research presented in this thesis focused on development of appropriate procedures for constructing and testing the model slopes and on calibration of the tilt apparatus. In this research, primary focus was given to determination of the model construction procedures that produced models that fail reliably and in a manner similar to field failures, evaluation of end effects in the models, and selection of an appropriate frictional interface that would allow for installation of reinforcement in future models. Forensic analyses of the "failed" models were conducted to determine the model properties at failure and then establish a calibrated computer model for predicting failure of the models to be tested with the device. It was concluded achieving repeatable failure of slope models proved to be difficult, but possible. An effective procedure was established for construction and testing of model slopes in the tilt apparatus. The fiber interface was determined to be the most suitable of the interfaces tested. Finally, a calibrated theoretical model was established to predict failure of future models.
