软弱围岩隧道变形控制与施工控制

Tunnel Deformation Control and Construction Control of Weak Surrounding Rock

软弱围岩区域隧道工程施工,由于特殊的地质条件因素的影响,极易形成大形变问题,对隧道结构体施加较强的外部应力荷载,导致结构失稳与破坏等系列问题。鉴于此,针对这一问题从理论与方法两个层面进入深入的研究分析,作为工程实践的参考依据。在分析软弱围岩变形问题的基础上,重点阐述了相应的变形与施工控制方法,旨在提供一定的参考与借鉴。

Due to the special geological conditions, it is easy to form a large deformation problem, and a strong external stress load is applied to the tunnel structure, which leads to the series of problems such as structural instability and failure.In view of this, the need for this issue from the theory and method two levels into the in-depth research and analysis, as a reference for engineering practice.On the basis of analyzing the deformation problem of weak surrounding rock, the corresponding deformation and construction control methods are emphasized, and the aim is to provide some reference and reference.
