摘要
在重庆寸滩集装箱码头基桩质量控制中,运用超声波成像技术获取高分辨率的波速图像,对基桩缺陷进行诊断。该技术在确定因施工造成的基桩缺陷的尺寸和部位方面,具有分辨率高、缺陷定位准确、检测结果直观、图像清晰等特点,为基桩整体质量评价与补强提供可靠的依据。
The tomographic diagnosis technology was employed in damage test of foundation piles of Chongqing Cuntan Container Terminal. Based on high resolution velocity images of concrete damage, the quality of concrete foundation pile was diagnosed. The measuring result of Cuntan Terminal foundation piles indicated that this technology is characterized by high resolution, accurate damage positioning, direct inspection result, and clear image, etc., and thus provides a reliable basis for quality evaluation and control of foundation piles.
