摘要
桥梁桩基作为地下基础,因其隐蔽性而不易检测,常用的声波透射检测法缺乏直观性,且所受干扰因素太多,而数字式全景钻孔电视具有成像直观、图像清晰、方法简便的特点。文中以大桥桩基检测为例,简要介绍数字式全景钻孔电视的技术原理,并结合工程实例,展示了数字式全景钻孔电视在检测中的优势。
Hie foundationasa kind of underground infrastructure, is veryhardinflawinspection.Cross hole sonic logging, the widely used methodin pile foundation inspection, lacks ofintuition, while the numeric panoramic borehole television technologycan easily get intuitionistic livepietureoftheborehole. Based on realprojeetcase, discussed simply the basic tech- nical principle ofnumeric panoramic borehole television, and its excellentperformance inpilefoundationinspection.
