| 摘 要： | 在采用管棚支护的隧道施工中地表沉降主要由管棚施工地表沉降和隧道开挖地表沉降组成。文章结合厦门高崎下穿公路隧道的工程实际,运用现场量测和理论分析的手段,对大管棚施工引起的地表沉降规律进行了研究;现场监测数据也证明,通过公式计算能有效地预测大管棚施工引起的地表沉降,其计算分析结果具有一定的实用价值。

| Abstract: | The ground settlements in a pipe-roof tunnel are induced by the construction process and tunnel excavation.This paper studies the laws of ground settlements caused by the construction of a large pipe-roof tunnel based on site measurements and theoretical analysis using the Gaoqi Tunnel under the existing highway in Xiamen as an example.The results show that ground settlements caused by the construction of a large pipe-roof can be effectively predicted by the calculations. |
