中文摘要：
采用盾构法进行隧道施工，难免会引起地层移动而导致不同程度的沉降，而采用Peck公式进行沉降预测时，首先要利用实测数据对该公式进行验证，并给出适合该地域的计算参数。文章利用合肥轨道交通盾构施工中的地表监测数据对Peck公式进行验证，同时计算出沉降槽宽度参数和地层损失率，为该公式在合肥盾构施工过程中预测地表沉降值提供了依据。
英文摘要：
The application of shield tunneling method in tunnel construction will inevitably generate the strata movement, whieh will lead to different degrees of settlement. When using the Peek formula for settlement predication, the formula needs to be verified by the experimental data. And the calculation parameters suitable for the region should be gotten. In this paper, the formula is verified by the sur- face monitoring data of Hefei metro shield construction. And the trough width parameter and volume loss ratio are calculated. The study provides a basis for the predication of the value of surface settle- ment in the process of shield construction in Hefei.
