摘要
为确定非对称建筑荷载作用下的小净距离隧道的合理施工方法,以某城市非对称建筑荷载作用下的公路隧道为基础,考虑预留核心土弧性导坑法、CRD法两种施工方案,通过有限元分析软件ANSYS,构建二维弹塑性模型,重点分析了隧道开挖对围岩的扰动效应,包括围岩位移以及水平应力两方面。
In order to determine the reasonable construction method of the small clear distance tunnel under asymmetric building load,taking the road tunnel under the asymmetric building load of a certain city as the foundation,considering the reserved core soil arc guide method and CRD method two construction schemes. The finite element analysis software ANSYS was used to construct the two-dimensional elastoplastic model. The disturbing effects of tunnel excavation on surrounding rock were analyzed,including the displacement of surrounding rock and horizontal stress.
