| Abstract: | Longlingong tunnel in Yi-Wan Railway is characterized with the complicated geological conditions and the full development of karst. In the course of construction, a multitude of dissolved cavities are found, including several large- scale rare ones. This study sums up some technological methods by which the typical dissolved cavities are treated, con- struction is achieved and the relative risks are avoided, which can be reference to other similar projects. |
