摘要

由于地质条件复杂，中国中西部地区的隧道建设面临巨大挑战。富水区的存在影响了开挖面的稳定性，导致潜在的安全风险和经济损失。本研究通过数值模拟对营盘山特长隧道进行了研究，重点关注不同条件下的应力和位移变化。主要重点是评估水对隧道稳定性的影响，尤其是在富水条件下。研究针对不同的施工阶段提出了有效的评估方法。研究结果为未来的工程项目提供了宝贵的指导，从而提高了隧道施工的安全性和效率。

Numerical simulation analysis of the stability of the construction face of a super long tunnel under conditions of precipitation and abundant water

Tunnel construction in central and western China presents significant challenges primarily due to the complex geological conditions. The presence of water-rich zones compromises the stability of excavation faces, leading to potential safety risks and economic losses. This study investigates the Yingpan Mountain extra-long tunnel through numerical simulations, focusing on stress and displacement variations under varying conditions. The primary focus is on assessing the influence of water on tunnel stability, particularly under water-rich conditions. The study proposes effective evaluation methods for different construction stages. The findings offer valuable guidance for future engineering projects, thereby enhancing safety and efficiency in tunnel construction.
