Abstract	Highway slope is an important part in the design and construction of highway. Especially in the complex geological condition area, road slope disasters occur frequently. So the stability of road slope is very essential to the safe traffic and the safety of human lives and their properties along the road. After the analysis of the existing methods of deformation measurement to physical model of highway slope, this paper introduces the theory and application of digital close range photogrammetry in deformation measurement of highway slope models. An ordinary digital SLR camera is employed and multi-intersection photography is used to take images of slope model in the project. The photogrammetric bundle adjustment is applied to compute 3D coordinates of artificial deformation monitoring target points on the surface of slope model. Then the cumulative displacement of each deformation monitoring target point is calculated based on their object coordinates in order to provide underlying data for the design of road slope and analysis of rock and soil mechanics.
