The electrical measuring method is one of the methods to use for structural element's stress analysis in engineering. It's applied widely for its sizes is small, and measurement operation flexible, and accuracy high. The up-anchors of underground power house of TGP are important facilities used as the handing of a tower crane, so it must be examined in safety by loading experiment before using in production. All together, the stress and its change of up-anchors are monitored during the loading experiment. The achievements show that regularities are significant by real measurement using resistance strain gauges. The measured values are all in the allowable range. It shows that the up-anchors are safety.
