近年来随着南水北调东线、中线工程的相继开工建设,各地方配套调水工程也纷纷上马,小断面隧洞在很多大、中型水利工程中得到广泛应用。以山东省重点调水工程——胶东调水工程中一典型的小断面隧洞为例,介绍小断面隧洞塌方的处理方法,供有关人员进行小断面隧洞塌方处理时参考。 In recent years, with the commencement of the construction of the east and midline projects of the South-to-North Water Diversion Project, various supporting water diversion projects have been launched in succession. Small-section tunnels have been widely used in many large and medium-sized water conservancy projects. Taking a typical small section tunnel in Jiaodong water diversion project as a key water transfer project in Shandong Province as an example, the treatment method of small section tunnel collapse is introduced for reference when relevant personnel are involved in the treatment of small section tunnel collapse.
