Abstract：In order to study the dynamic response of the roadway by pressure relief role under the action of static and dynamic, the Chang village S61# was taken as the research object, and analyzed by FLAC 3D software.The results show: under static and dynamic loads, the floor heave displacement is increased by 92 mm compared with the static load, so that the phenomenon of floor heave is more serious.Under dynamic load, the new shearing yield and tensile-shearing yield is generated at the bottom corner of the model and at about 2 m from the bottom of the model.
