Slope StabilityThe stability of natural and man-made slopes is dependent on a number of factors, including site geology, slope inclination, strength of soils, construction activities, and ground shaking. Ninyo & Moore utilizes state-of-the-art computer programs to perform slope stability analyses for both planned and existing slopes, as well as to provide repair recommendations for slope failures. Typically, these analyses are conducted based on laboratory tests performed on samples obtained from exploratory excavations, such as borings or test pits. If a slope is found to have an inadequate factor-of-safety (i.e., less than 1.5 for engineered slopes), Ninyo & Moore has designed stability fills and buttresses to improve the stability of the slope so that it has an adequate factor-of-safety. Ninyo & Moore has utilized a number of stability methods to repair failed slopes and design new slopes. These methods include:

33 Bay Drive LandslideNinyo & Moore provided geotechnical consulting services during the evaluation and repair of active landsliding and damaged foundations for a bluff top home. The four-story home cantilevers outward over a coastal bluff, which includes an active landslide area. Several homes were destroyed during the past 40 years due to landslide movement. Landsliding resulted from adverse bedding within fine grain siltstone facies of the San Onofre... |
