摘要
桥梁方案比选是选择性能优越、造价经济建设方案的重要工作。以桥位通航要求复杂的某特大桥的初步设计方案为例,对预应力混凝土部分斜拉桥、波形钢腹板预应力混凝土连续梁、预应力混凝土连续梁桥3种桥型进行方案比选。从跨径布置、结构形式、景观构造、施工方案及工程造价等因素进行了探讨与比较,并选出了推荐方案,提出的轻量化设计充分发挥了钢-混材料的组合性能和延长了桥梁寿命,为该类环境的桥梁方案选择提供了一定的参考。
The comparison and selection of bridge schemes is an important work to select the construction schemes with superior performance and economic cost.The preliminary design scheme of an super major bridge with complex navigation requirements was compared for prestressed concrete Partial Cable-stayed Bridge,prestressed concrete continuous beam with corrugated steel webs and prestressed concrete continuous beam bridge three types.Then discusses and compares the factors such as span layout,structural form,landscape structure,construction scheme and project cost,and selects the recommended scheme,the proposed lightweight design gives full play to the combined performance of steel-concrete materials and prolongs the service life of the bridge,which provides a certain reference for the selection of bridge scheme in this kind of environment.
