澳門-氹仔第三桥的斜拉桥风载动力特性分析

由于桥址处台风多、风况复杂,为保证桥梁抗风安全,对主桥斜拉桥成桥状态、施工最大单悬臂状态进行了动力特性计算、风载内力计算和抖振响应计算,并给出了相应的计算结果。结果表明该桥无论是成桥状态还是施工状态均具有足够的抗风稳定性。

Analysis on Wind-Load Dynamic Characteristics for Cable-Stayed Main Bridge of Macau-Taipa 3rd Bridge

As the bridge site is of frequent typhoon and complicated wind conditions, to ensure the wind safety of the bridge, calculations are made on dynamic characteristics, wind-load internal force and buffeting response for completion state and max cantilever state in construction of the cable-stayed main bridge. Calculation results presented here show that the bridge is of enough wind stability under both under-construction state and completion state.
