The invention discloses a high-speed railway earthquake monitoring early warning and emergency disposal demonstration system. The system comprises a wave output device, a shake device, a high-speed railway sand table platform, an acceleration sensor and a high-speed railway earthquake monitoring cabinet, wherein the wave output device is connected with the shake device, the shake device is connected with the high-speed sand table platform, the high-speed sand table platform is connected with the acceleration sensor, and the acceleration sensor is connected with the high-speed earthquake monitoring cabinet. The system can simulate high-speed railway operation under earthquake conditions and also can carry out simulation experiments which are not allowed to occur in practice, so that experience accumulation and technical support are provided for safe operation of high-speed railways in earthquake environments, safety accidents are reduced or avoided in practice, and property losses and passenger life dangers are reduced.
