Abstract
Vibrating-wire strain gauges are widely used for the tunnel instrumentation because of the long-term stability at humid environments. Domestic strain gauges are mainly used in Korea due to the high cost of the foreign strain gauges. The credibility of the domestic strain gauges is not properly proven even though strain gauges produced by many different companies are available in the markets. The purpose of this paper is to investigate the credibility of the 2.5" strain gauges by using a laboratory compression test.
