Ground Improvement Techniques

Ground Improvement Techniques. Instructor: Prof. G. L. Sivakumar Babu, Department of Civil Engineering, IISc Bangalore. The soils at construction sites are not always totally suitable for supporting physical infrastructure such as buildings, bridges, highways, tunnels and dams. Under these conditions, soil needs to be treated using ground improvement techniques. Similarly specific types of soil improvement techniques are required in the case of expansive soils and collapsible soil and in the case of earthquake prone areas. The course addresses various ground improvement techniques along with principles, design issues and construction procedures. (from nptel.ac.in)
