摘　　要：广州国际会展中心主体砼结构部分为双向多跨超长大跨度肋梁板结构体系,且使用荷载较大。我们在结构中充分应用现代预应力砼技术,并根据结构中各主、次要结构构件的功能使用要求,把有粘结预应力砼技术和无粘结预应力砼技术结合应用,在不同的部位发挥各自的长处,很好地满足了设计及使用要求,且取得了非常好的经济效益。Two-way multi-span ribbed slab with big loads, which is super long and large-span, is applied in the main concrete structure of Guangzhou International Convention Exhibition Center. The modern prestressed concrete technology is employed in the design of the structure. According to the functional requests of the primary and secondary structure components, the bonded prestressed concrete technology and non-bonded one are applied together and taken advantage individually in different components. It is shown that the optimized design is successful and well satisfying with the functional request of the structure. And Good Economic benefit has been gained.
