| Abstract: | The Dongling tunnel of Shanzhan Highway is an extra long mountain tunnel with the single tunnel being4248m and the buried depth being 300m. It is the third longest tunnel among highways in Guangdong, which is ofcomplicated geographical conditions. In order to identify the level of the tunnel surrounding rocks, comprehensive investigationmethods were taken, including engineering-geological investigation and depiction, drilling, geophysicalexploration, and hydrographic geological experiment, etc.. |
