Stability analysis of slope with building loads

Abstract

In hill areas, landslides are frequent and hazardous. In developing hill areas, many multistoreyed r.c.c. farmed buildings are constructed on hill slope. The building loads are transferred to the hill slope terrain at the foundation level, which may cause hill slope failure. Therefore the stability of hill slope with building loads needs to be checked. In this paper, a procedure has been developed to find the factor of safety against sliding failure of slope considering building loads transferred to the slope. Earthquake forces can also be considered in the analysis. Different types of soils in the slope can be considered. A computer program has been developed based on the formulation presented in the paper and is validated by solving few examples. Stability of slope with differently configured buildings have been studied. Provisions to be made for stepped foundations on hill slopes has been highlighted here.
