Convergence Deformation Monitoring for Diversion Tunnel during Construction at Sopladora Hydropower Station in Ecuador

厄瓜多尔索普拉多拉水电站导流洞施工期收敛变形监测按照"新奥法"施工的基本理念,在分析施工条件的基础上,提出了导流洞的施工收敛监测布置方案。通过对典型断面收敛监测变形成果进行分析,了解到该隧洞施工期收敛变形呈衰减形和直线形发展,为施工期围岩支护措施的设计提供了参考。

For convergence deformation monitoring for diversion tunnel during construction at Suopuladuo in Ecuador,based on basic concept of 'New Austrian Tunneling Method,NATM' and analysis on construction conditions,layout scheme for convergence monitoring during construction of the diversion tunnel is presented.By analyzing convergence deformation monitoring on typical section,it is confirmed that the convergence deformation of the diversion tunnel during construction is attenuating and linear.This gives reference to design of surrounding rock support measures during construction.
