| Zusammenfassung: | The invention discloses a composite test simulation device for suspension tunnel earthquake and flow-induced vibration. A suspended pipeline model is supported by a steel frame pedestal such that bothends are located in rock and soil and subjected to earthquake action, and the middle part is subjected to hydrodynamic action in water to realize the simulation of the structural dynamic response process of the suspended tunnel under the coupling of earthquake and hydrodynamics; the simulation device can achieve differential simulation through two vibration tables; in the simulation device, the suspended pipeline model is in a suspended state to more accurately simulate the state of the suspended tunnel during actual operation; and the cable spring model used by the simulation device can moreaccurately realize the elastic simulation of the anchor cable. The device provided by the invention can reasonably and accurately simulate the earthquake motion and flow-induced vibration simultaneously.
