Effect of Placement of Footing on Stability of Slope

Abstract

- Due to land limitations and increase in population, peoples are utilizing slopes (natural or manmade) for construction
purpose. In such situation, when construction is carried out on slope without analyzing the stability and bearing capacity, slope
may result in failure. The present scenario at Uttarakhand in India is one of the examples of slope failure. Many people lost their
lives and property in Uttarakhand disaster. Footings of bridges abutments, foundations near to excavations, retaining walls and
electric transmission towers built on mountain slopes are the obvious examples of footing on slope. In this paper focus is made on
analyzing the slope for different locations of footing, and loading conditions. Analysis indicated that any stable slope may become
unstable if new construction activity was carried out near as well as on the slope. The slopes were found to be stable for gi ven soil
condition and slope up to certain load, beyond which it becomes unstable. The stability of slope was found to be maximum when
load was placed at middle of slope.
