摘要

堤坝防渗墙的质量安全关乎国计民生,寻求有效方法快速检测防渗墙缺陷十分重要。弹性波映像法是基于弹性波反射原理的无损检测方法,具备检测效率高、结果直观等特点。针对堤坝防渗墙的常见缺陷类型,以弹性波在堤坝模型中的传播特性为理论基础,采用数值模拟方法分别分析了弹性波在防渗墙竖向通缝缺陷、防渗墙深度不足、空洞缺陷处的传播特性,根据计算结果建立响应能量与防渗墙缺陷之间的关系,为堤坝防渗墙缺陷的检测提供了一种快速的评价方法。
        Both quality and safety of levee cut-off walls are very important for the nation's economics and people's daily activities, therefore, effective and fast testing methods of the integrity of these levee cut-off walls are necessary. The elastic wave imaging method is a non-destructive testing method based on the elastic wave reflection principles and it has the advantages of high efficiency and direct testing results. Based on the elastic wave propagation in the levee theory, this paper presents the numerical analysis results for different types of defects that are commonly encountered in the construction, such as, vertical throughout joints, cut-off wall that does not reach its design depth, and voids in the concrete. The relationships between the response energy and the defects in the levee cut-off wall are established. It is possible to provide a fast defect testing method for the integrity of the levee cut-off walls.
