摘　　要：水下衬砌基础破坏无损检测是目前水下检测工作的一个难题。为解决水下衬砌结构和基础破坏检测问题,利用Biot-Stoll理论深入分析了水声信号在水下破坏介质中的传播规律,同时结合声波数值模拟分析了不同衬砌基础破坏的声学信号反射特征,给出了进行基础破坏检测的声学参数。实际水下衬砌基础结构破坏检测案例表明,基于水声信号的水下衬砌基础结构破坏检测技术可有效分析水下衬砌基础破坏类型及破坏范围。The damage detection of underwater concrete infrastructure is a difficult issue in the current underwater detection work.In order to solve the issue of underwater concrete structure and underwater foundation damage detection,this paper used the Biot-Stoll theory to deeply analyze the propagation law of underwater acoustic signals in the medium.At the same time,it combined with the sound wave equation numerical simulation to analyze the acoustic signals of different underwater foundation damage features and gave the range of underwater acoustic parameters for underwater foundation damage detection.Combined with an actual underwater lining damage case,the characteristics of the underwater acoustic signal were theoretically analyzed.The article effectively analyzed the damage type and the scope of the underwater foundation damage,and proved the effectiveness of the underwater acoustic signal for the detection of underwater lining foundation damage.
