超声波检测在王集引黄闸安全鉴定中的应用研究

Application of ultrasonic detection in the safety appraisal of Wangji Yellow River diversion sluice

现行水闸安全鉴定中,一般水闸混凝土结构强度均是按照回弹及碳化测量结果进行推定,但该方法有其局限性,无法合理估计混凝土内部情况,对水闸复核计算也难以做出严谨的评价。超声波检测以其无损、快捷的方式可以大范围在水闸混凝土结构中运用,能够较为准确的对混凝土情况进行推断,以某水闸安全鉴定实例,对超声检测及复核计算结果进行分析,以供实际应用和研究参考。

In the current sluice safety appraisal, the general sluice concrete structure is inferred based on the rebound and carbonized measurement results, but this method has its limitations. It can’t reasonably estimate the internal conditions of the concrete, and it is difficult to make a rigorous evaluation on the sluice review calculation. Ultrasonic testing can be used in a large area of sluice concrete structure in a non-destructive and fast way, and can more accurately infer concrete conditions. This article uses a sluice safety appraisal example to analyze the results of ultrasonic testing and recheck calculations. Practical application and research reference.
