Comparative study of design parameters in pre and post construction of earth retaining structure to enhance durability

Abstract

Landslides are major natural disasters. It a ects the ecosystem and results in economic loss. The Konkan region from Maharashtra, India also experiences this problem every year. To prevent from such disasters the slope stabilization tech- niques are used, among which the retaining structure provision is one of them. Most of the time permanent RCC earth retaining structure (ERS) is provided. These structures are constructed for total serviceability period of 30-60 years but generally in most of the cases in lateritic soil, they cannot withstand for their total serviceable life. To nd out the reasons of failure and to increase serviceability period, a detailed investigative study of engineering geological and geotechnical properties was conducted to assess the serviceability or structural safety of can- tilever earth retaining wall at Dasgaon and Sahilnagar from Mahad Tehsil, Konkan region Maharashtra and the preventive measures from the failure of cantilever ERS are discussed.
