The invention provides a two-dimensional extrusion stretching device. The invention belongs to the field of geological environment simulation experiment equipment. An opening is formed in the upper end of a sand box, the sand box is used for placing an extruded substance for an experiment, the sand box comprises push plates which are symmetrically arranged at the two ends in the X-axis direction,the push plates move in the X-axis direction to extrude an object in the sand box, and an observation window is arranged in at least one side in the Y-axis direction of the sand box and used for observing the extruded state of the object in the sand box. According to the invention, the state that sandy soil is only subjected to extrusion/tensile force in the horizontal X direction is simulated, the simulation result is more accurate, and the accuracy and effectiveness of experiments are ensured. 本发明提供了二维挤压拉伸装置，属于地质环境的模拟实验设备领域，包括上端开口的砂箱，用来放置实验用的受挤压物质，所述砂箱包括在X轴方向的两端对称设置的推板，所述推板在X轴方向移动，对砂箱内的物体进行挤压，所述砂箱Y轴方向的至少一侧设有观察窗，用来观测
