| 摘 要： | 钢管混凝土脱空是一种常见的缺陷,脱空缺陷直接影响其耐久性和可靠性。为了探测钢管混凝土内部的情况,可以用超声检测方法估计脱空厚度。根据超声检测的声时和现场钻孔测试相结合,把数据进行直线回归拟合,可以快速准确地判断钢管混凝土拱肋的缺陷。在实际工程中具有实用价值。

| Abstract: | Cavity is a common defect in concrete filled steel tube(CFST) and it directly influences the durability and reliability of CFST.In order to find out the internal state of CFST,the empty thickness can be estimated by using ultrasonic inspection(UT) method.Based on combination of sound time from UT and test performance of in-site drilling,the data was processed by line-fitting method,which could justify the flaws in the CFST accurately and quickly.This new method had practical application in engineering,and h... |
