摘要
在长隧洞施工中使用掘进机(简称 TBM)具有诸多优点,但在岩溶洞段,溶洞的处理是个十分棘手的问题,还没有较成熟的技术和经验,一般在掘进过程中先临时加固,待通过后再进行永久加固处理。为此,介绍了引黄工程国际Ⅰ,Ⅱ标段岩溶段的技术处理方法。
TBM is commonly used in long tunnel excavation for its advantages.Unfortunately,there were no mature techniques and experiences for dealing with karst in construction.Normally,temporarily reinforcement is made during excavation,and permanent support after excavation.In this paper,some techniques are presented for dealing with karst in international bid Ⅰ and Ⅱ of Shanxi Yellow River Diversion Project.
