| 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... |
