摘要

针对高密度面波法在堆石体结构密实度检测中的检测指标及评价标准问题，基于堆石体结构的典型功能层结构建立2维有限元模型，综合考虑了不同密实度类型，模拟高密度面波检测过程，并对数值模拟结果进行频散分析，建立在不同密度堆石层中波的传播速度与堆石体结构密实度的相关关系.以吴淞导堤堆石坝为对象，实施高密度面波法现场数据采集及分析，详细介绍了堆石体结构检测中的实施过程及数据处理方法，通过频散分析及构造反演，得到导堤结构的速度深度分布，并利用速度-密实度相关关系对导堤结构密实度的空间分布进行了评价.

Abstract：

In order to clarify the detection index and evaluation standard for evaluation of the density of rockfill using high-density Rayleigh-wave exploration, a series of 2-D FEM models with different density of rockfill based on typical function layer were established. The Rayleigh-wave exploration was simulated to obtain the relationship between propagation velocity in rockfill with different density and density of rockfill by frequency-wave number analysis. Besides, the highdensity Rayleigh-wave exploration is applied to the investigation of the Wusong Jetty in Shanghai. The data acquisition and analysis method were introduced in detail. The distribution of velocity with depth was obtained by dispersion and inversion analysis. Finally, the spatial distribution of density was evaluated according to the relationship between velocity and density of rockfill.
