【摘要】 考虑了隧道周边收敛与掌子面的推进距离以及拱顶下沉与周边收敛之间的关系,利用半解析法和随机介质理论建立计算模型对隧道变形进行预测,以宁武高速福安隧道为工程背景验证其正确性,表明该方法效果良好,有一定的工程价值.更多还原

【Abstract】 Taken into account the relationship between peripheral convergence of tunnel and propulsion distance of section, and, also, vault crown settlement of tunnel, meanwhile, based on semi-analytical method and the theory of random medium calculating model can be established, which can be used to predict deformation of tunnel. Taking Fuan, the tunnel’s name, included in highway of NingWu as a project case, which proves that such model can predicts efficiently and has a certain value of engineering.更多还原
