试论盾构隧道施工地表沉降规律及控制措施研究

Elementary Discussion on Surface Settlement Law and Control Measures of Shield Tunnel Construction

在使用盾构法进行隧道施工时,常常会导致隧道上部的地表出现沉降,并在隧道的运营过程中,这种沉降现象依然会持续发展,对隧道的地下设施以及隧道四周的地面建筑都会造成较大的影响。所以,降低施工对周围土体的干扰,分析隧道施工时地表的沉降规律至关重要。基于此,对盾构隧道施工地表沉降规律以及控制措施进行探讨研究。

Tunnel construction by shield method often results in the surface settlement above the tunnel, and in the operation process of tunnel, this kind of settlement will still be sustained to develop, which will cause the greater influence on the underground facilities of tunnel and the ground buildings around tunnel.Therefore, it is very important to reduce the disturbance of construction on the surrounding soil body and analyze the settlement law of the surface in the tunnel construction. Based on this, the article discusses and studies the surface settlement law and control measures of shield tunnel construction.
