盾构法施工在隧道工程施工领域得到了广泛的应用，特别是对于复合盾构，能克服很多的复杂地层完成隧道施工，盾构机本身的掘进能力也不断得到完善和提高。然而，针对不同的困难地层，隧道施工更多地应该采用不同处理方案，为盾构机顺利通过创造条件。本文根据工程实践经验，就硬岩段隧道采用矿山法施工完成后，盾构空推可采用的两种施工工艺进行对比分析。“,”Shield method construction has been widely applied in the field of tunnel construction, especially for the composite shield,which can overcome a lot of complex formation and complete tunnel construction.Shield-driven tunneling machine itself is constantly being refined and improved. However, for different kinds of difficult ground, tunnel construction more should adopt different solutions, creating conditions for the shield successfully passed. This article is based on practical experience, respect of hard-rock tunnels with mine construction is completed, to compare and analysis two construction techniques of pushing the shield.
