摘　　要：厦门机场路环岛南路立交低桥位匝道桥的波浪力计算和结构计算表明,该处需要设置竖向预应力来抵抗波浪力上托力的作用,并论证该结构的可行性和适用性,为类似工程提供经验。The calculations for wave force and structure in low-location ramp bridge of overpass on south road to the island on Xiamen Airport Road show that this location shall be equipped with vertical prestressed structure to withstand the impact of uplift force in wave force. This paper demonstrates the feasibility and applicability of this structure so as to provide experiences for projects of the same type.

关 键 词：桥墩 竖向预应力 波浪力 防波堤
