下穿隧道与涵洞合建节点处理

Treatment of Combined Construction of Undercrossing Tunnel and Culvert

文章对下穿隧道与河道平面交叉的竖向关系进行分析,针对合建和分建两种可能的方案,以某隧道和涵洞合建为例,模拟分析合建节点的受力情况,根据三维计算结果,给出合建节点处的工程方案,并提出合理化建议供类似工程建设参考。

This paper analyses the vertical relationship of undercrossing tunnel and channel plane in view of two possibe solutions of combined construction together and separated construction. Taking the combined construction of tunnel and culvert as an example, stress distributions of joint is simalated. According to the results of three-dimensional calculation, the engineering scheme is proposed, rationalization proposal to similar project are put forward.
