结合某隧道实际工程,通过软弱围岩隧道塌方段施工处治技术,从工程地质、水文地质及施工因素等各方面分析其发生塌方灾害事故的原因,归纳出围岩塌方的破坏特点,并对相应处治措施作出分析评价。结果表明:施工中采用超前小导管、锚杆超前支护等措施,对防止围岩恶化,控制隧道变形和预防塌方能起到明显作用。
結閤某隧道實際工程,通過軟弱圍巖隧道塌方段施工處治技術,從工程地質、水文地質及施工因素等各方麵分析其髮生塌方災害事故的原因,歸納齣圍巖塌方的破壞特點,併對相應處治措施作齣分析評價。結果錶明:施工中採用超前小導管、錨桿超前支護等措施,對防止圍巖噁化,控製隧道變形和預防塌方能起到明顯作用。

With a tunnel as the background,the reason and mechanism of the tunnel collapse are researched and analyzed from many factors such as engineering geology,hydrological geology and construction,the destruction characteristics of the collapse are induced,and the analysis and evaluation are made for the corresponding treatment measures.The results indicate that some measures as supporting with small guide tubes and archor rods and so on used in construction could play the obvious roles in preventing the surrounding rock from worsening and controlling the tunnel distortion and lanslide.
