摘要
埋深大、线路长的隧洞采用TBM施工,已成为国际上快速开挖隧洞的主流.引黄工程南干线4#～7#隧洞总长90 km,除部分进、出口土洞段外,全部按TBM施工.沿线水文地质条件复杂、埋深大、单条隧洞长达43 km.结合工程施工实践,对TBM施工要点地质洞段的施工对策进行了探讨.
TBM is commonly used for deep buried and long tunnels and becomes prevailing technique for tunnel excavation in international practices.The total length of No.4～7 tunnels in South Main of Shanxi province Yellow River Diversion Project(YRDP)is 90 km.The tunnel is excavated by TBM except some soil entranceways. The longest tunnel is about 43 km and hydrological geology of the tunnel is quite complex.According to practical experiences,some construction countermeasures are discussed for TBM constructions in bad geological sites of engineering.
