Structural Integrity Assessment of Submerged Bridges Using Robotic Inspection and Scour Survey

Ashish Antony Jacob, Vineet Upadhyay, Shanmukha Kavya V, and Tanuj Jhunjhunwala, discuss advanced structural assessment of submerged portions of bridges and the limitations posed by alternate methods.

In a developing country like India, roads, rails and bridges are amongst the most important infrastructure assets that connect every corner of the country. Roads and bridges tend to undergo wear and tear with aging. When they get submerged, they are susceptible to further damages such as scouring, rebar exposure, corrosion, cavities etc. Hence, periodic inspection of bridges is essential to detect early deterioration and to schedule maintenance and restoration plans to prolong their life, prevent catastrophic damages, and loss of lives.
