摘要
隧洞施工过程中,地质人员应根据隧洞开挖揭露的最新地质情况,及时作出地质预判,并提出相应的工程处理方案,确保施工安全.采用赤平投影法和Unwedge软件分析法,对同一隧洞围岩稳定性进行了对比分析,结果表明Unwedge软件具有可视化强、操作方便等诸多优点,值得在隧洞工程施工地质工作中得以推广应用.
During tunnel excavation,geologists should give the geological prediction based on the geological conditions of tunnel,and propose engineering support methods to ensure the safety of tunnel construction.Comparative analysis of stereographic projection and Unwedge is conducted in the same tunnel for the stability analysis of rockmass.The comparative analysis shows that Unwedge has advantages of better visualization,more convenience for operation,etc.The application of Unwedge is expected to be promoted in geological construction during tunnel excavation.
