汶川地震灾区文家沟特大地质灾害防治引水隧洞设计与动态施工

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

摘要:

对汶川地震诱发的文家沟特大泥石流，采取引水隧洞工程进行治理，是四川省地质灾害治理应急抢险项目，时间紧、任务重，在没有时间进行详勘的前提下，利用动态施工管理，采用各种手段和方法获取信息，根据开挖时发生的应力、应变特性，给出适合该地质条件的施工方法和支护结构。介绍了该引水隧洞的设计及动态施工技术措施。

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.
