摘要

对隧道开挖引起的地表沉降模型进行总结，详细地调查和分析了金丽温高速公路红枫连拱隧道工程区的地质特征，系统研究了在偏压条件下连拱隧道开挖引起的地表沉降规律，对红枫隧道开挖引起的地表沉降进行研究，建立了偏压条件下连拱隧道分步开挖引起的地表沉降预测模型，对不同开挖工况下的差异沉降进行分析，证明该预测模型比较真实的反映了在偏压及浅埋条件下连拱隧道开挖引起的地表沉降规律，为浅埋连拱隧道开挖过程中防止地表过度变形提供理论基础。

Abstract

The ground surface settlement models caused by tunnel excavation are summarized. The discontinuity plane geological characteristics of Hongfeng doubled arch tunnel in Jin-Li-Wen Expressway are investigated and analyzed. The ground surface settlement rule cased by excavation of doubled arch tunnel in case of partial pressure is researched. The ground settlement of Hongfeng doubled arch tunnel during excavation is analyzed. The ground surface settlement models of difference excavations by step for doubled arch tunnel in case of partial pressure are built. The difference settlement of different excavation is analyzed. The ground surface settlement models testified that it forecasts the ground surface settlement of excavation for Hongfeng doubled arch tunnel in case of partial pressure and shallow overburden. It provides a theoretical basis for avoiding overmuch settlement during excavation of shallow doubled arch tunnel.
