中文摘要：
拱坝坝肩岩体的稳定与否直接关系着拱坝的安全。我国西南锦屏一级拱坝坝肩工程地质条件极为复杂,对其处理措施中设置了密集的7层洞室。采用VisualGeo工程地质三维建模系统,建立该工程整体岩级分类三维地质模型,并建立抗力岩体加固处理洞室群模型。在此基础上进行坝肩边坡模拟开挖分析及抗力岩体加固处理洞室群模拟开挖分析,得到加固处理洞室群围岩岩级分类三维地质模型。同时,进行坝肩洞室群所在的7个高程的平切分析和各洞室开挖各类岩体的体积分析,为高拱坝坝肩岩体处理设计与施工提供了直观、精确的可视化分析平台。
英文摘要：
The stability of the abutment rock mass is directly related to the stability of the arch dam. The abutment of the Jinping I Arch Dam situated in the Southwest China is in a complex geological condition, whose treatment measures contain 7 layers of dense cavities. The VisualGeo 3D modeling system was adopted to establish the 3D rock mass classification geological model of the project and to establish the cavities model of the resisting rock masses reinforcement. Based on the models, simulated excavations of abutment slope and cavities reinforcement of the resisting rock masses were performed; the 3D rock mass classification geological model of reinforcement cavities was obtained, and slicing analyses of the 7 elevations was undertaken. A precise visual analysis platform was presented for the design and construction of high dam abutment treatment.
