Analysis and Risk Assessment of Structures on Hilly Areas: Case of Pune, India

Abstract

Hilly areas have certain risk factors that are neglected. It may happen due to uneven development and improper construction. Risk assessment of an area helps to analyze events that impact on environment, people and property to judge risk analysis and factors influencing it. These areas are usually occupied when flat land is not available or rates of land on flat ground are high. Due to this, there is a chance of unplanned growth of settlements. Hilly areas have steep slopes and the site has more number of weaknesses and threats like rock falling, landslides, soil erosion and many more. By doing this study, we can become aware of the risks which are not much taken into consideration but do make a major difference, secondly we can try to develop better construction methods which could overcome these risks and provide safety for these structures. Also long life of the structures is ignored because no one is able to consider the future state of the area. To carry out this analysis, a case study of Pune is taken; the hilly areas of Ambegaon are recently developing drastically. The research is done after the damage caused in the vicinity by heavy rainfalls during the monsoon season 2019.
