FIELD MEASUREMENTS OF THE BEHAVIOR OF INCLINED FOOTINGS ON A NATURAL SLOPE

Full-scale field testing for the bearing capacity and stability of inclined footings with anchors was carried out on a colluvial slope near the east portal of the Rogers Pass tunnel in British Columbia. The 35 deg natural slope was composed of granular material with an angle of shearing resistance equal to 40 deg. A series of small footings (area 1.14 sq m) was loaded with anchor loads only and one large footing (area 2.66 sq m) was loaded with both anchor and vertical loads up to 2100 kN. Bearing capacity coefficients were back calculated and compared with coefficients from bearing capacity theories. Elastic and deformation moduli were calculated from load-displacement curves during loading and unloading and creep rates were observed at intervals during the tests.
