摘要
本文主要介绍了某电站施工支洞塌方段针对地质条件和现场施工条件，采用超前小导管注浆加固与型钢相结合的方式处理，取得了良好效果，对类似工程的处理提供了借鉴。
The paper mainly introduces solution for dealing with construction adit collapse in one hydropower station, where advanced small pipe grouting technique is applied in conjunction With profile steel for treatment based on the geological condition and site construction condition. This method works effectively and provides experiences for other similar projects.
