桥梁基桩施工工艺对基桩质量及超声无损检测的影响

Influence of Construction Technology of Bridge Foundation Piles on Quality of Foundation Piles and Ultrasonic Nondestructive Test

由于受工地现场多变的天气、复杂地质条件以及施工过程中不规范施工工艺的影响,桥梁基桩的病害不断出现,因此高效快捷的灌注桩超声脉冲检测法成为检测基桩病害较为准确可靠的技术之一。根据工程实践,对一些受不规范施工工艺影响的基桩质量及其超声检测结果进行总结和分析,供同行参考。

Due to the influences of inconstant weather on site, complicated geological conditions and irregular construction technology during construction, the diseases are constantly occurring to foundation piles of bridge, so high-efficiency and rapid cast-in-place pile ultrasonic pulse detection method becomes one of the accurate and reliable techniques for detecting foundation pile diseases. Based on the author ＇ s working practices and experiences, this paper concludes and analyzes quality of foundation piles affected by irregular construction technology and ultrasonic detection results for reference by colleagues.
