摘　　要：格里桥水电站厂房位置下移后，引水系统需穿过原厂房位置处的古河床底部，引水系统存在地质条件较复杂、布置条件有限、引水隧洞洞径较大、压力钢管边界条件复杂等特点。充水运行后，发现隧洞渗水量较大。对隧洞混凝土裂缝、结构缝及隧洞与压力钢管接头处进行处理，处理后引水隧洞外水压力明显减小，运行未发现异常。After the powerhouse of Geliqiao hydropower project slided down, the headrace tunnel had to cross the bottom of the ancient riverbed where the powerhouse was located before and encountered problems such as complex geological conditions, limited layout conditions, large tunnel diameter and complex surrounding conditions of the penstock. Large volume of leak was found in the tunnel ＇ s water delivering operation. After treatments on concrete eracks, structural joint and joint between tunnel and penstock were finished, the outer pressure on the headrace tunnel decreased and no abnormal conditions was found in the operation.
