Abstract: Based on structural plane information collected on-site using noncontact photogrammetry technology, a dummy grid was proposed to establish a roadside rock slope spatial block model utilizing a random structural plane to cut the slope. The model was inserted into a 3-dimensional analysis system (GeoSMA-3D) developed by the authors in order to conduct roadside rock slope key block search and analysis. Calculations showed that the model could dynamically add structural planes and readily establish geometric models for complicated steep rock slopes, as well as analyze key blocks on certain roadside slopes in Liaoning Province.
