摘要： 在现场结构面非接触摄影技术采集的基础上,提出基于虚拟网格的、采用随机结构面切割岩体的方法,建立了岩质边坡空间块体模型.并将该模型接入作者团队自主开发研制的三维数值分析系统GeoSMA-3D,进行岩质边坡关键块体搜索和分析.算例表明:该模型具有可以动态添加结构面、易于建立复杂岩体边坡几何模型等优点,并对辽宁某边坡进行了关键块体分析.

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.
