摘　　要：V型连续刚构-拱组合桥是将拱圈与V型墩刚构刚性连接,共同承担荷载的新型桥梁体系。该桥型受力性能良好、造型新颖,具有广阔的发展前景,但其结构复杂,在设计计算、施工控制方面难度较大,对其进行施工监控是保证桥梁施工质量和施工安全的关键。目前,V型刚构-拱组合桥在国内的研究还处于起步阶段,缺乏完善的规范体系和成熟的经验,在设计、施工监控、荷载试验、施工技术上均存在一些技术难点。该文以寨子坪大桥为例,对其施工监控、成桥荷载试验进行介绍,可供业内人士参考。The V-shaped continuous rigid frame-arch composite bridge is a new type of bridge system that rigidly connects the arch ring and the V-shaped pier rigid frame to jointly bear the load.This bridge type has excellent mechanical performance,novel shapes,and broad development prospects,with a complex structure,however,causing difficulties to design calculations and construction control.Therefore,construction monitoring is the key to ensuring bridge construction quality and construction safety.At present,the domestic research on the V-shaped rigid frame-arch composite bridge is still in its infancy,lack of a complete specification system and mature experience,with some technical difficulties in design,construction monitoring,load testing,and construction technology.Based on the Zhaiziping Bridge case,this paper introduced its construction monitoring and bridge load test,which can be used as a reference for the industry.
