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。介绍了引黄工程国际I、II标段岩溶段的技术处理方法。
Adopting TBM in the construction of the long tunnel possesses many advantages, however the treatment of the solution cavity in the karst cave section is a very difficult problem, people has no any mature technique and experience, generally, people makes tenlporary reinforcement at first in the course of the tunneling, and then makes permanent reinforcing treatment. This paper introduces the solution cavity treatment technique used in the karst cave section of YRDP Project＇ Ⅰ and Ⅱ international tender sections.
