摘要盾构掘进诱发上覆管线的挠曲和脱空分析对其结构保护至关重要。基于双层Winkler地基并考虑管线上覆与下卧地基刚度差异，对盾构隧道开挖上覆管线挠曲和脱空进行理论与模型试验证实分析。基于荷载板试验对传统管线砂土地基承载理论加以修正，提出适用于盾构穿越管土相互作用分析的砂土地基刚度和极限承载力取值建议。参数分析发现，管线脱空宽度随管线抗弯刚度和隧道开挖地层损失增大而变大，但变化速率递减；当地层损失或管线抗弯刚度较大时，管土线弹性相互作用理论和考虑界面脱空的单层地基计算方法均高估了管线挠曲和弯矩，而考虑界面脱空的双层Winkler地基计算方法可更准确地预估管线挠曲。

Abstract：The assessment of deflection and voiding resulting from shield tunnelling on overlying pipelines is critical for safeguarding their structural integrity. A method for calculating such deflection and voiding during shield tunnel excavation，taking into account variations in stiffness between the pipeline?s overlying and underlying subgrades，was developed using a double-layer Winkler foundation model. Model tests verified its applicability. Conventional subgrade bearing theories for pipelines buried in sand were refined based on plate load tests，providing recommendations for stiffness and ultimate bearing capacity relevant to soil-pipeline interaction during shield tunnelling. Parameter analysis revealed that void width increases with pipeline flexural stiffness and tunneling ground loss，albeit at a decreasing rate. Significantly，under conditions of high ground loss or pipeline flexural stiffness，both the soil-pipeline elastic interaction theory and the single-layer foundation method，considering interface voiding，tend to overestimate pipeline deflection and bending moments. In contrast，the double-layer Winkler foundation method，incorporating interface voiding，delivers a more precise prediction of pipeline deflections.
