Shear Strength Characterization and Stability Assessment of Urban Open-Pit Mine Slopes
The City of Irwindale, California, contains a series of open-pit sand and gravel mines that have been excavated over the past century. These mines are located in a broad alluvial fan consisting of noncohesive silt to boulder size materials with significant fractions larger than 100 mm. An extensive characterization program was implemented to develop design shear strength values for use in slope stability analyses. This program revealed very high frictional strength, which is largely attributed to dilatency. Some apparent cohesion also is present. This design strength envelope was then used to evaluate the static and seismic stability of existing and proposed slopes.
