盾构法同山岳岭法及明挖法相比较,对周围环境的影响小,并且从施工时的安全性,以及能缩短工期等有利因素考虑,盾构法成为过密化城市条件下构筑隧道的基本施工方法。本文就有关盾构掘进式隧道技术的现状,降低建设成本和提高施工效率及今后课题作一介绍。 Shielding method compared with the mountain ridge method and open cut method, the impact on the surrounding environment is small, and from the construction safety, and can shorten the construction period and other favorable factors, the shield method to become a city under the conditions of dense tunnel construction Basic construction methods. In this paper, we introduce the status quo of shield tunneling technology, reduce the construction cost and improve the construction efficiency.
