    Slope Stabilization for Local Government Engineers in Minnesota
    (2017-05) Nelson, Mitchell
    Slope failures cause infrastructure damage, pose safety risks, and produce preventable maintenance costs. The purpose of this research was to recommend methods for stabilizing locally-maintained slopes requiring recurring maintenance in Minnesota. The author used input from county and municipal engineers to determine common techniques and identify slope failure examples. Site investigations helped develop case studies to analyze slope stabilization methods. Laboratory testing characterized representative soil strength properties. Additionally, the author developed Limit Equilibrium Method models for each slope to investigate different stabilization methods in a parametric study. Finally, modeling and analysis results were summarized in a guide for local government engineers. The target audience of the guide is county or local municipal engineers that do not have specialized geotechnical engineering experience. Additionally, modeling software enabled the development of slope stability charts specific to roadway embankments. The stability charts and guide will assist engineers in improving slope stability for roadway embankments.
