Design of Diversion Tunnel for Serious Geological Disaster Prevention in Wenchuan Earthquake Area and the Dynamic Construction

Abstract:

The diversion tunnel was used to deal with the serious Wenjiagou debris flow induced by Wenchuan earthquake. According to the dynamic management thinking, various means were taken to get the information. Based on the stresses and the strain characteristics, the construction methods and the support structure suitable to the geological conditions were determined. The paper introduced the design of diversion tunnel and the technical measures in dynamic construction.
