The present invention discloses a lining member quasi-static test apparatus and a lining member quasi-static test method. The lining member quasi-static test apparatus comprises a reaction force device, a loading device, a lining member and a surrounding rock simulation system, wherein the reaction force device comprises a reaction force wall and a reaction force steel frame, a sliding support seat is arranged above a vertical jack, the lower portion of the vertical jack is connected to the lining member so as to apply a static load and simulate the eccentric compression state of the lining member, a horizontal actuator is connected to the top portion of the lining member so as to apply a dynamic load and simulate the action of the repeated load applied on the lining member, a spring is arranged on the right side of the lining member so as to simulate the constraint action of the surrounding rock, and by changing the type of the spring and disassembling the local spring, the different levels of the surrounding rock, the surrounding rock softening, surrounding rock voiding and other surrounding rock conditions can be simulated. According to the present invention, with the apparatus and the method, the dynamic and static coupling effect of the lining member can be simulated, the lining member back cavity and other defects can be simulated, and the advantages of test economy, simple operation, strong reliability and the like can be provided.
