| Abstract: | Tunnels in the swelling rock region are easy to collapse,which is a threat to the safety.Combined with the practical project of Duguidele reilway tunnel,we have put forward some effective measures to quarautee its quality.Practice shows that these measures are valid in reducing the large landslides.Similar projects can take it for reference. |
