Abstract

Abstract: Construction countermeasures, including strengthening the support of the horizontal adit, adjusting the roof ripping construction organization, optimizing the construction techniques, optimizing the design of the junction section of the main tunnel and strengthening the management, are adopted, so as to achieve safe and rapid construction of the junction section between the horizontal adit and the main tunnel. In the end, safe construction is guaranteed, the cost is reduced, the roof ripping construction period is shortened to 7 days and the rapid roof ripping construction of No. 13 and No. 14 horizontal adits is realized.

Key words: Sanlian tunnel, soft ground, junction section, rapid roof ripping
