摘    要:以某大堤堤身空洞检测为工程背景,基于Flac3D方法,对有空洞的堤身模型堤身空洞位置与弹性波中的纵波与横波的传播关系进行计算分析.结果表明:可以通过横波的传播引起大堤表层质点振动发生延迟的水平坐标范围,判断出堤身空洞的水平位置范围;通过纵波的传播引起大堤表层质点振动发生延迟的水平坐标范围,判断出堤身空洞的深度位置范围.研究结果可为采用地震波法进行大堤空洞缺陷位置检测过程中堤身空洞缺陷位置的初步判断提供参考.

关 键 词:空洞  横波  纵波  检测

Abstract:In this paper, under the engineering background of levee hollow detection, based on Flac3D meth- od, the relationship between holes position in some levees with holes and primary wave and secondary wave are analyzed. The analytical results show that through the horizontal coordinates" range of vibration delay at surface particle due to the secondary wave propagation in the holes, the horizontal position of holes in levee will be determined; by means of the horizontal coordinates range of vibration delay at surface particle due to the primary wave propagation in the holes, the vertical position of holes in levee will be determined. The re- search results will give references to position detection of holes in levees by seismic wave.
Keywords:holes  primary wave  secondary wave  detection
