基于Peck公式的隧道施工实时地表沉降预测研究

Based on the Peck Formula of Tunnel Construction Prediction Surface Subsidence in Real Time

随着城市化的发展,地面交通压力越来越大,越来越多的城市开始发展地下交通轨道,不可避免地会实施隧道工程,由此引起的地表沉降是我们不得不重视的问题。本文以山东省某地铁隧道工程为研究对象,利用实测数据分析研究由此引起的地表沉降规律。一般认为peck公式只能对下沉最终值进行预测,本文将依据peck公式对隧道施工过程中的地面沉降值进行实时预测,结合实测数据,我们可以发现peck公式可以很好地预测隧道施工过程中的地表沉降规律。

With the development of urbanization, more city began to develop underground track to copy with pressure of ground traffic. It is importance to attach that the surface subsidence because of underground traffic engineering. Now, taking a subway tunnel project in Shandong Province as the research object, using the measured data analysis the rule of surface subsidence. Based on the peck formula of tunnel construction prediction surface subsidence in real time, combining with the measured data, we can find that peck formula can weU predict the surface subsidence rule in the process of tunnel construction.
