摘　　要：基于某高速公路特大桥高墩施工实践,对高性能混凝土强度进行检测与评定。按照设计配合比拌制混凝土制作试件,检测混凝土试件强度并进行了回归分析。通过对施工现场墩身混凝土强度检测结果进行分析,得出抗压强度满足设计要求,施工质量合格。Based on the construction practice of high piers of an expressway bridge,the strength of high-performance concrete was tested and evaluated.According to the design mix ratio,the concrete was mixed to make specimens for curing,the strength of the concrete specimens was tested and regression analysis was performed.By analyzing the test results of the concrete strength of the pier at the construction site,it is concluded that the compressive strength meets the design requirements and the construction quality is qualified.
