| 摘 要： | 混凝土工程是电站枢纽工程最重要的组成部分之一,是工程安全的基础和保障,确保混凝土实体质量、杜绝混凝土质量缺陷是电站安全稳定运行的基本保证。随着声波检测技术水平的提高,并已在大坝混凝土工程中得到广泛应用。通过大量混凝土实测抗压强度和声波波速值对比试验的数理统计分析,建立工程专用测强曲线,能有效提高混凝土抗压强度推算值的准确性,较真实地反映混凝土实体质量水平。

| Abstract: | Concrete engineering is one of the most important part of hydropower complex project and the foundation and guarantee of project safety.Ensuring concrete entity quality and eliminating concrete quality defects are the basic guarantee for safe and stable operation of hydropower plant.With the improvement of sound wave detection technology,it has been widely used in dam concrete engineering.Based on the mathematical and statistical analysis of a large number of comparative tests between the measured compressive strength and sound wave velocity of concrete,the special strength curve for engineering is established,which can effectively improve the accuracy of the calculated compressive strength of concrete and reflect the quality level of concrete entity. |
