综合法检测T梁混凝土强度研究
Strength Test of T-Shaped Concrete Beams Based on Comprehensive Method
摘要
Abstract
The strengths of T-shaped concrete beams at a railway showed problems when tested by the single detecting method.However,the strengths of 12 T-shaped concrete beams of two bridges (A and B) at the railway met the design requirements tested by the comprehensive method.The principle and results of two detecting methods were compared,which suggested that several indexes of the comprehensive method are essential for the evaluation of concrete strength of important structures.The comprehensive method showed the advantages of being economical,lower testing error,and higher accuracy.It is an important approach to evaluate the quality of concrete structures such as bridges and foundations,which can provide scientific basis for decision making and has important significance in assessment of the quality of engineering and construction.关键词
