The utility model relates to a slide rail device for an engineering test, which comprises a soil preventing box, rolling wheels, a roller bearing and a guide rail, wherein the rolling wheels (2), the roller bearing (3) and the guide rail (5) are covered in the soil preventing box. Each roller is connected with the soil preventing box to form integration through the roller bearing of a shaft center of the rolling wheels, and is fixedly connected with a horizontal loading plate (4) through the soil preventing box. In addition, the rolling wheels are positioned on the guide rail. The rolling wheels can also horizontally roll along the guide rail. The guide rail device can be used for guiding the horizontal loading plate to horizontally move in a simulation test of the urban underground engineering in the course of horizontally loading. The utility model which is a constituent part of a three-dimensional loading simulation test device can effectively reduce the friction force of the horizontal loading plate and a bottom plate of a box body of a simulation box and decrease the friction force to horizontally load a model test of a large scale underground engineering, improves efficiency and leads the simulation test device to flexibly load horizontally under the condition of minimal friction force. The utility model is also suitable for other mechanical guide rail devices which need to reduce friction, with strong versatility.
