30m混凝土连续箱梁静载试验研究

大跨度后张法预应力混凝土连续箱梁在高速公路建设中以其卓越的技术、经济性能而得到广泛应用。对30m混凝土连续箱梁在静荷载作用下其应力—应变、挠度以及裂缝等情况进行了详细论述,通过准确的试验数据说明试验梁的承载能力满足设计及规范的要求。

Static Load Test on 30m Concrete Continuous Box Girder

The post-tensioned prestressed concrete continuous box girder with large span has been widely used because of its excellent technical and economic performances.This paper discusses in detail the stress-strain,deflection,and fissure,etc.of 30 m concrete continuous box girder under the static load,and through the accurate test data,illustrates that the bearing capacity of the test girder meets the requirement of the design and the specifications.
