不同断面近距离区间隧道施工顺序分析研究

Researchonconstructing order of the different close distance section tunnel

从是否有利于施工的角度出发,同时通过ANSYS有限元软件,对重庆轻轨大坪区间不同断面近距离隧道开挖顺序进行详细分析,结果表明:先施工小断面隧道比先施工大断面隧道更有利,并邮施工实践所检验。可为其它城市地铁区间隧道施工提供借鉴。

From whether to benefit construction and using ANSYS analysis software, this paper analyses in detail the constructing order of the different close distance section tunnel and the result shows that it is better to construct large tunnel first than small one. Its application resulted in the successful construction of Chongqing Daping light-railway section tunnel. All this can be taken as a reference for the similar tunnels.
