Strain gauge electrical measurement technology as a nondestructive testing methods widely used in various engineering structures. Hydraulic concrete structure commonly used method to detect the loading process of stress state. However, the resistance strain gauge test results by the temperature, humidity, conductor length and other environmental factors. In order to improve the reliability and accuracy of strain gage measurement technology for hydraulic concrete and to expand its application range, the article summarizes some practical experience and puts forward some improvement measures for the reference of relevant personnel. In order to further promote the hydraulic concrete electrical measuring The application of technology provides the experimental basis
