摘要
利用面波在浅部土层中的传播特性以及面波相速度与岩土力学参数的相关性,采用多道瞬态面波法对勘察场地进行探测,通过数据处理获得场地的面波相速度剖面,根据面波相速度结构来推断场地内回填土的分布范围。钻探资料表明,多道瞬态面波法探测结果可靠,应用效果良好。
Based on the propagation of the surface wave in shallow strata and the correlation between surface wave phase-velocity and geotechnical parameters, the authors employed MASW to make engineering investigation, obtained the surface wave phase-velocity pro- file through data processing, and inferred the backfilling range of the field according to the surface wave phase-velocity structure. Drill- ing data show that the transient MASW is reliable and can yield good results.
