水电站导流洞施工在不良地质条件段开挖时容易发生多次塌方,结合具体工程实例,对塌方段工程地质条件和塌方情况进行分析,找出了塌方原因,最后提出了处理措施,为同类工程导流隧洞塌方的预防和处理提供了一定的参考依据。
The construction of diversion tunnel of hydropower station is prone to multiple landslides during excavation under unfavorable geological conditions. Combined with specific engineering examples, the engineering geological conditions and landslides in the landslide are analyzed to find out the causes of landslides. At last, the treatment measures are provided for the similar Engineering diversion tunnel collapse prevention and treatment provided some reference.
