摘要
由于现浇板出现裂缝 ,为保证其安全 ,对缺陷性现浇板进行了现场荷载试验 ,由此得到了现浇板在正常使用荷载作用下产生的短期挠度、开裂情况及残余变形 ,从而确定了现浇板的工作性能 ,为缺陷性现浇板的后期使用及加固处理提供了依据。
Owing to the produced joint in poured-in-place slab,site load test of defect poured-in-place slab was made for its safe.By this,short-term deflection,crocking performance and residual deformation of pour-in-place slab are obtained under normal working load.And working performance of poured-in-place slab was determined.Foundation is provided for its latter periode working and reinforcement.
