The invention relates to a surveying device for measuring horizontal displacement of a soil body. A tension part is tightened between the upper and lower ends of a surveying pipe, distance measuring sensors are distributed in the length direction of the surveying pipe in an interval mode and connected with data collection and treatment device, and the horizontal distance between the distance measuring sensors and the tension part is measured by the distance measuring sensors, and distance information is sent by the distance measuring sensors to the data collection and treatment device to treat. When displacement of the soil body is appeared, the surveying pipe is transformed, so the distances between the distance measuring sensors fixed on the wall of the surveying pipe and the tension part are changed, and change value of each collected distance information and depth position of sensors are computed by the data collection and treatment device; therefore, horizontal displacement curveof the soil body can be drawn, and the aim of automatically and accurately monitoring is achieved. Due to adopting cheap distance measuring sensors replacing expensive tilt angle sensors, the monitoring cost is greatly reduced.
