| 摘 要： | 盾构隧道施工不可避免地对隧道周围地层产生扰动，从而产生地层损失和路基沉降，路基沉降分析是盾构隧道的一个重要方面。基于Peck公式，逐步推导出单洞盾构隧道下穿铁路轨道路基沉降槽宽度系数的计算公式，从而对Peck公式进行修正，并结合福州地铁一号线的监测数据进一步验证了修正后的Peck公式的合理性和适用性。

| Abstract: | Shield tunnel construction inevitably disturbs the surrounding strata, thus producing formation loss and roadbed settlement. The analysis of roadbed settlement is an important aspect of shield tunnel. Based on Peck equation, calculation formula of width parameters of roadbed settlement trough of single-tube shield tunnel passing under the railway track were gradually deduced, which modified the Peck equation. The rationality and applicability of the modified Peck equation was further verified combined with the monitoring data of Fuzhou city subway line 1. |
