摘　　要：以某双连拱隧道为工程背景,采用有限元法,建立连拱隧道结构及围岩分析模型,重点研究在偏压荷载条件下连拱结构的应力分布特点,并研究了不同围岩类型及地质条件对结构应力分布的影响。The finite analysis model is established for a twin-arched tunnel and the surrounding rocks. The focus of study is on the features of stress distribution of the twin-arched tunnel structure under the sloping loads. In addition, the effect of different types of rocks and geological conditions on the stress distribution of structure is discussed.
