摘要

目前混凝土裂缝检测常用的超声波法和冲击回波法仅限于浅裂缝。本文基于自我校正的傅里叶透射系数法,提出了检测大体积混凝土裂缝深度的R波谱能量透射比法,并对含不同深度表面裂缝的混凝土试块进行试验和数值模拟,研究传感器位置、不同裂缝分布数目及间距对R波谱能量透射比的影响,得到不同裂缝深度与谱能量透射比之间的回归关系。该法可以用于大体积混凝土裂缝的检测。

Abstract

When identifying the depth of cracks in mass concrete structure, especially those with great depths, the impact echo method and ultrasonic methods always fail due to the rapid energy attenuation of P wave. In this paper, Surface Wave Spectral Energy Transmission Ratio (SETR)method is used to estimate the depths of surface-opening deep cracks in concrete. The effect of distance between transducers and the number of cracks on surface wave transmission ratio is investigated through experiments and FE analysis. It is found that the SETR can be effectively used for the crack depth estimation of concrete structures.
