摘要
预应力混凝土连续箱梁桥是目前中小跨径最主要的桥型之一。针对这一桥型施工过程中关键技术作了详细论述。主要包括采用塑料波纹管、真空辅助压浆、超长空间钢束施工工艺。结合这种预应力施工工艺在嵊州长安大桥建设中的成功应用,可予以推广。
Prestressed concrete continuous box girder bridge is regarded as one of the primary middle-small span bridge types at present.Its key construction techniques have been mentioned in detail in the paper,including plastic corrugated pipe,vacuum supporting grouting and super-length space steel bar.And the prestressing construction techniques should be promoted with its successful application of Chang'an Bridge,Shengzhou.
