【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。
[Abstract]:Using shield method in tunnel construction will inevitably cause stratum movement and result in different degrees of settlement. When using Peck formula to predict the settlement, the formula should be verified by the measured data. The calculation parameters suitable for the region are also given. This paper verifies the Peck formula by using the surface monitoring data of Hefei rail transit shield construction, and calculates the parameters of settlement trough width and formation loss rate, which provides the basis for predicting the surface settlement value in the course of shield tunneling construction in Hefei.
