| Abstract: |
| Physical model test is an important research means in the research field of geotechnical engineering,This article used a two-dimensional physical model simulation studies for underground mining. At first, under the premise of the similarity theory, determine the ratio of similar materials, according to the engineering geological conditions, elect the appropriate profile as a research object model, then piling, excavation, deformation observations, ultimately concluded the deformation law of surrounding rock when the underground mining. finally summed up the direction of the displacement vector of the observation point on the surrounding rock in underground mining, deformation law and the scope of the impact of excavation. |
