| Abstract: | Advanced geological prediction contributes to understand structural changes of wall rock in front of tunnel face and possible geological disasters in advance, and to take targeted construction countermeasures and modify construction plan so as to avoid dangerous situations. For right line of Yingzuiyan Tunnel, this paper by reference to advanced prediction result adopts small duct leading support and reinforced support with I18 I-beam bracket to remove fills in karst cavities and processes karst chamber with backfilling and takes method of reserving drainage channels to eliminate hidden dangers. |
