摘要
高速公路桥梁因长期运营和早期技术限制出现结构问题。通过青兰高速女姑口特大桥为例,探索研究预应力孔道定位、自密实混凝土施工、体外成品预应力索安装、预应力损失测定与补偿4项关键技术及施工工艺,解决了现场实际问题,同时提高此类工程施工水平,为今后类似工程施工总结经验。
Highway bridge has suffered structural problems due to long-term operation and early technical constraints.Through qinglan high-speed female large bridge as an example,explore the prestressed channel positioning,self-compacting concrete construction,in vitro product prestressed cable installation,prestress loss determination and compensation four key technology and construction technology,solve the practical problems,and improve the level of such engineering construction,summarize experience for similar engineering construction in the future.
