剪切波测试技术在输水管道工程勘察中的应用

摘要

利用单孔检层法对南水北调配套工程元氏—赵县输水管道的岩土基础进行剪切波速度测试，判别基础地震液化情况，通过对现场实测的数据分析第四系砂壤土、粉细砂、中砂的剪切波速值等物理参数，可较准确地判别工程场地的类别和地震液化。%For shear wave velocity test using of single-hole detection layer method to rock and soil foundation of Yuanshi—Zhaoxian County water pipeline of the South-to-North water diversion project can distinguish the foundation of seismic liquefaction, shear wave velocity and other physical parameters of Quaternary sandy loam, fine sand, medium sand and other physical parameters will be based on the value of the field measured data. Categories of engineering site and earthquake liquefaction can be recognized accurately through this method.
