京昆高速河北省石家庄至晋冀界T梁试验研究

Experimental Study on Reinforced Concrete T Beam of Beijing–Kunming Expressway from Shijiazhuang to the Border of Hebei and Shanxi

对京昆高速河北省石家庄至晋冀界质量存在疑问的T梁采用超声回弹综合测试法进行了钢筋混凝土梁的混凝土强度测试,并对其中1片T梁进行非破坏性静载试验,将测试结果进行综合分析,对测试梁的强度和承载力进行客观评价,最终将测试梁应用于施工现场,节省工程资金,排除安隐患。

The strength of reinforced concrete T beams in Beijing - Kunming Expressway from shijiazhuang to the border of Hebei and Shanxi was tested with the ultrasonic-rebound method. A non-destructive static load test for one of the T beams has been done. The results show that the beams are up to specification, and can be used for the construction.
