Abstract: The present disclosure provides a fire test system and method for tunnel structure based on real-time fusion of numerical and physical spaces. The fire test system includes: a physical test unit, to perform a holographic fire test on the typical segment components of tunnel structure system in a physical space, to obtain holographic characteristic parameter data of the typical components; a numerical analysis unit, to establish a full-scale numerical model of the tunnel-stratum composite system in a numerical space, to obtain multi-field coupling boundary data of the typical components; and a fusion control unit, to control and adjust a multi-field coupling boundary of the physical space according to the multi-field coupling boundary data, and to update and adjust an input parameter of the numerical space according to the holographic characteristic parameter data.

Abstract: This application provides a resonator that includes a housing and a cover. A resonant rod, a dielectric block, and an elastic element are disposed in the housing. The resonant rod is in a tubular shape and includes an inner side face, an outer side face, and a first end face. The dielectric block includes a bottom end and a top end, the top end is connected to the cover, a second end face and a boss that protrudes from the second end face are disposed at the bottom end, and the boss is in an annular shape. The boss is embedded in the resonant rod a, or the boss fits around the outside of the resonant rod. The elastic element is connected between the first end face and the second end face or between the top end of the dielectric block and the cover.
