摘要
长江大桥的施工往往位于长江阶地,长江阶地具有砂层厚的特点。武汉某长江大桥桥梁桩基工程采用超声波无损检测技术,对所有桩基进行检测,并采用超声波检测、钻芯和凿洞开挖等综合手段,详细查明个别桩基浅部声测管包裹沙团、泥块的现象,保证了桩基工程质量,对类似工程具有很好的借鉴性。
Yangtze River Bridge construction is often located in the Yangtze River terraces, and the Yangtze River terraces with the characteristics of thick sand.Wuhan Yangtze River Bridge Pile Foundation Engineering uses ultrasonic nondes- tructive testing technology to detect all pile foundation, and as well as uses ultrasonic testing, coring and borehole excavation in a comprehensive way, and then makes detailed identification of individual pile foundation shallow acoustic tube wrapped Sand Mission, clod phenomenon, to ensure the quality of the pile foundation engineering, which has a good reference for similar projects.
