【摘要】 我国作为山地较多的国家,同时也是目前公路隧道修建最多的地方。随着经济的进一步发展,目前已建的部分隧道逐渐不能满足交通量的需求,在原有公路隧道基础上改扩建显得尤为迫切。以大条山隧道为背景,通过利用MIDAS-GTS软件进行有限元分析法,计算不同隧道支护参数下隧道周边收敛及拱顶下沉位移,得出合理的设计施工方案。更多还原

【Abstract】 Taking a tunnel as a background, this paper had the finite element analysis method by MIDASGTS software to calculate the surrounding convergence of the tunnel and vault subsidence displacement under the different tunnel supporting parameters, and it also concluded the reasonable design and construction scheme.更多还原
