摘要： 依托西藏某水电站工程，集成导流隧洞空间优化布置技术，采用地质三维软件Geostation对断层带进行精确模拟，并对导流隧洞洞线进行空间优化布置，采用FLAC3D“混合离散”方法分析断层带对导流隧洞的影响。研究表明，通过优化布置，可减少断层带在导流隧洞中的出露长度，提高导流隧洞围岩稳定性，缩短工期，节约工程投资。

Abstract: Geological software Geostation is used in a hydropower project in Tibet to accurately simulate the faults and to optimize the axis line of the diversion tunnel. The mixed discrete method in FLAC3D is used to analyze the influence of faults and to provide the basis for spatial optimization of the tunnel line. By optimizing the layout, the exposed length of the faults in the diversion tunnel is reduced, stability of surrounding rock is improved, the construction period is shortened, and the project investment is saved.
Key words: diversion tunnel, complex geology, spatial optimization, 3D simulation
