浅埋隧道在开挖过程中不可难免的会引起地表沉降。预测及计算沉降量，经验公式形式简单，但所需参数不易获得；数值计算结果直观，但建模复杂，缺乏通用性。运用ABAQUS针对实际工程进行数值计算和经验公式进行比较分析，数值计算得到的沉降曲线与Peck沉降曲线形状相同、参数吻合，并与实际情况接近。将数值计算和经验公式相结合，选择合适的数值计算结果，反推经验公式参数后回代经验公式，可以比较方便地得到地表沉降规律，预测地表沉降。

It is inevitable to cause the ground surface settlement during the excavation process in the shallow tunnel .Predicting and calculating the settlement ,it is difficult to get the parameters of empirical formula ,although its form is simple .Numerical calculation result is intuitive ,but its modeling is complex and can′t be widely used .This paper carries on the comparative analysis be‐tween the numerical calculation and empirical formula based on a practical project using the ABAQUS .The results show that the settlement curve made by the numerical simulation and Peck settlement curve are the same in the shape ,also with the same parameters ,and close to the actual situation .When combining numerical calculation and experience formula ,choosing the ap‐propriate numerical settlement result and back calculation the parameters of empirical formula , the ground surface settlement rules can be gotten and predicted conveniently .
