摘要

研究目的：水中悬浮隧道是一种新型的穿越水域的固定交通设施，当悬浮隧道穿越水道较宽时，需要在两岸之间设置支撑系统。支撑系统设置是否合理直接关系到悬浮隧道的稳定性和修建成本，因此本文特对此进行分析。

研究结论：流速和漩涡发放频率对悬浮隧道支撑系统间距的影响最为明显;悬浮隧道振动高阶失稳的极限跨度比低阶失稳的极限跨度大;该方法亦可用于支撑系统位置评判设计是否合理。

Abstract

Research purposes: Submerged floating tunnel is a new type of fixed transport facility for crossing waterways and always needs support system between the banks to make it stable when it crosses broad water area. It not only affects the structure's stability but also affects the building coat whether the support system is set up reasonably or not.

Research Conclusions: The current velocity and the vortex frequency influence the support system length mostly. The unstable criterion of the support of the high order for submerged floating tunnel is larger than that for low one. The Melnikov method can be used for judging whether the allocation of support system is reasonable or not.
