Steel pipe concrete arch frame coupling performance detection and evaluation method, and steel pipe concrete arch frame coupling performance detection structure

The present invention relates to a steel pipe concrete arch frame coupling performance detection and evaluation method, and a steel pipe concrete arch frame coupling performance detection structure. The method mainly comprises: completing engineering main body construction, adhering a strain sheet on the steel pipe outside the steel pipe concrete arch frame, determining the strain value of the steel pipe outside the arch frame under the wall rock pressure, determining the damage amount of the concrete inside the steel pipe through an acoustic emission technology, calculating the steel pipe concrete coupling coefficient of the steel pipe concrete, comparing the damage conditions of the steel pipe and the concrete, and comprehensively analyzing the steel pipe concrete coupling performance of the steel pipe concrete arch frame. According to the present invention, the evaluation method is simple and is easy to perform; and with the calculation of the steel pipe concrete coupling coefficient Kf of the steel pipe concrete arch frame, the steel pipe concrete coupling performance of the steel pipe concrete arch frame can be intuitively evaluated.
