摘要
针对在役先张法空心板梁底板的纵向裂缝病害,专门进行了大量板梁桥的现场调查和检测。在调查基础上,进行了裂缝分布、性状和有关参数的归纳统计,初步探明了纵向裂缝的分布规律,并对病害成因、影响进行了定性的分析探讨,为后续深入的研究和处治对策提供参考。
To analyze the longitudinal cracks diseases on the bottom of existing pretensioned hollow slab beam,this paper specially made a large number of field investigations and detections on plate girder bridges.On the basis of the investigations,the crack distribution,characteristics and related parameters were summed up.It initially proved the law of the distribution of the longitudinal cracks and made a qualitative analysis and discussion for the cause and impact of the disease.It provided detailed and rich information for subsequent further study and treatment measures.
