摘　　要：通过实地勘察和室内试验,分析了不同地质条件对盾构掘进的影响。研究表明:地层软硬不均、地下水丰富和断层破碎带是主要难点。针对这些问题,提出了优化刀具配置、改进注浆工艺和采用变量控制等对策。实践证明:这些措施能有效提高施工效率和质量,为复杂地质条件下盾构隧道施工提供了可靠的技术支持。Through field surveys and indoor experiments,the impact of different geological conditions on shield tunneling was analyzed.Research has shown that uneven hardness of geological layers,abundant groundwater,and fractured fault zones are the main challenges.In response to these issues,measures such as optimizing tool configuration,improving grouting technology,and adopting variable control have been proposed.Practice has proven that these measures can effectively improve construction efficiency and quality,providing reliable technical support for shield tunnel construction under complex geological conditions.
