＂5.12＂汶川地震发生后,渔子溪水电站道路、通讯一度中断,首部枢纽、引水隧洞、厂房（生活区）、尾水渠、尾水出口、GIS楼等均遭受严重损坏。2009年4月27-28日引水隧洞放空检查时发现衬砌段混凝土出现大量裂缝,底板出现管涌等现象;未衬砌段出现岩体下落、危岩体增多等情况。对震后引水隧洞的震损分析及如何快速修复等作了全面阐述,为类似工程的实施提供了可供借鉴的经验。
After May 12 Earthquake occurred,once roads were discontinued and communications were disrupted.Headworks,headrace tunnel,powerhouse(living quarter),tailrace channel,tailrace outlet and GIS building were damaged severely.From April 27th to 28th,2009,headrace tunnel was emptied for inspection,a large number of cracks were found in concrete lining section and piping occurred in tunnel invert,rock falls happened in non-lining section and dangerous rock mass increased.In this paper,a general description was made for seismic damage analysis of headrace tunnel and its rapid rehabilitation measures to provide references to the similar projects.
