摘　　要：结合工程实际需求,提出在湖底隧道顶设人行景观桥的桥隧结合方案,并通过分别建立平面框架模型和三维板单元模型,进行内力分析和比较,结果表明采用平面框架模型计算结果更为保守,可确保工程安全。另外还提出了桥墩处隧道顶防水解决方案,可为类似工程提供参考。Combining with the actual needs, a bridge-tunnel combination scheme of pedestrian landscape bridge constructed on the crossing-lake tunnel is proposed. The plane frame model and three-dimensional plate element model are established to analyze and compare the inner forces. The results show that the calculation result of the plane frame model is more conservative and can ensure the engineering safety. And the waterproofing solution of the tunnel roof at bridge piers is also proposed. The experience can be referred for the similar projects.
