Paper Abstract

Scour is a very severe problem for bridge. In this paper, a bridge scour monitoring system based on active thermometry is proposed. The monitoring system fulfills scour monitoring based on the different patterns of temperature change between in liquid and in solid after heating due to their distinctive heat transfer behaviors. It utilizes a thermal cable to generate heat with a heating belt and concurrently measure temperature with DS18B20s. Several experimental tests were conducted using the system. Results confirm the methodology and substantiate the scour monitoring system.
