印度尼西亚阿萨汉一级水电站引水隧洞施工测量

Introduction of Construction Survey for Headrace Tunnel in Asahan No.1 Hydroelectric Power Project in Indonesia

结合工程实践,介绍了印度尼西亚阿萨汉一级水电站引水隧洞在开挖与混凝土衬砌过程中测量的主要技术和方法,并就如何提高隧洞贯通精度、较好控制隧洞超欠挖问题提出了建议,探讨了断面收方技术在隧道围岩变形监测中的应用.

The principal survey technique and method for excavation and concrete lining of the headrace tunnel in Asahan No.1 Hydroelectric Power Project are introduced based on construction practice.And the authors also give their own opinion on how to improve the breakthrough precision of tunnel to control underbreak and overbreak of tunnel excavation.Moreover,the application of statistic techinque to deformation monitoring of surrounding rock in the tunnel is discussed.
