摘要
盾构隧道叠交施工有一个重要现象,即在没有欠挖或过量压浆等施工因素的影响下地面仍然会降起,对此作了解释,并提出了地面隆起变形公式。将该公式和地面沉降的派克(Peck)公式进行叠加,给出了盾构隧道叠交施工地层移动的数学模型,其数值结果与现场测试结果基本一致。
It has an important phenomenon, that the ground will still heave without the influence of lacking excavation or over grouting etc. for the overlapped shield tunnel. This paper ex-plains it and supplies the deformation formula of the heaving ground, superposing the formula to the Peck formula, and then get the mathematics model of the layer movement of the over-lapped shield tunnel, and the results are basically consistent with the result tested in site.
