摘要
地基基础处理、尤其是灌浆施工,采用常规的钻孔取芯、压水试验、孔内电视法等方法对其质量进行检测具有较大的局限性,难以全面而准确的进行质量评价,本文通过实例介绍了孔间超声波层析成像法在此类"隐蔽工程"施工质量检测中的应用,获得了剖面内较准确的波速指标分布,物性量化,用数据说话,同时也便于统计分析,检测成果较好地指导了施工处理和工程设计。
Foundation treatment, expecially grouting effect test,Usually, it have greater limitations when use the testing methods such as core drilling, hydraulic pressure test, bore-hole televiewer, it is difficult to conduct a full scale and accurate quality evaluation.This paper describes the examples of the application of ultrasonic tomography method in such ＂hidden project＂ construction quality test,and concluded accurate velocity profiles,the physical properties is quantified, using data to prove, it is also facilitated to statistical analysis, the test results can be as a guide to construction treatment and engineering design.
