The bearing capacity of soils on a rock foundation has been researched by L. Jurgenson. W. Hartmann for a large ratio of loadwidth to soil thickness and M. Livneh for its small ratio, neglecting the soil-weight and approximately treating friction between soils and surfaces of a footing and a rock foundation. Now these studies are based on the theories of metal plates with finite area, though soil layers have infinitesimal area. Percieving the fact that part of soils rise around a footing, whereas the above studies assume that all of them move horizontally, the author newly found the exact slip line fields and calculated the bearing capacity of them under the conditions that soil-weight is negligible and sticking friction is acted between soils and surfaces of a footing and a rock foundation. Then the theoretical solution is comfirmed by some experiments.
