Non-invasive Diagnostic Methods for Structural Health Monitoring of Concrete Gravity Dams—Case Study of Umiam Dam
Dams are an integral part of a nation’s assets that provide various benefits in the form of irrigation sources, drinking water supply, flood moderation, power generation, recreation, maintaining flow in the river, industrial use, etc. In addition, there are instances that the dam tops also serve as roads for public transportation thereby causing additional vibration load on the dam body, which is random, periodic or dynamic in nature. Though these forces are minute in nature, yet capable of causing distress in the dam body over the service period of the dam. Anticipated damages on account of failure of dams can be in terms of loss of life, loss of property, natural environment, etc. apart from hampering economic development. Ageing dams need extra care due to distress and long-term stability issues. This paper highlights the potential of vibration engineering technique to monitor the operational safety of the structure over periodic intervals and nondestructive assessment of the quality of concrete. One such hydraulic structure that serves as road for public transportation is the Umiam Dam, forming a part of National Highway-40, linking states in the north-eastern region. Owing to transportation use of the dam top since decades, vibration measurements and in-situ quality assessment has been conducted, to verify the operational safety of the structure. With ever-increasing traffic, owing to economic developments, it is anticipated that distress in the structure may increase abnormally that warrants for prior remedial measure such as diversion of bulk carrier through an alternate by-pass road to safeguard the dam.
