| 摘 要： | 港口与航道淤泥层层界确定对于港航建设开发与工程实施有着重大意义。本文针对港口航道浅地层剖面仪原始采集数据模糊的问题,分析了影响原始数据真实性的主要原因,实施了中值滤波法多次波压制与消噪处理,取得了清晰可靠的真实数据图像文件,根据海底声波不同层界反射特征,对比分析了脉冲信号声强图像变化情况,探讨了基于浅剖数据声强图像提取淤泥层厚的方法。试验证明该方法可以达到当前钻孔资料所能达到的精度范围。

| Abstract: | Port and waterway silt layers determination is of great significance for the development and implementation of the harbor construction project.Based on the fuzzy problem of the original data collection of sub-bottom profiler, analyze the main reasons affecting the authenticity of the original data, process the median filter multiple attenuation and de-noising, clear and reliable real data image files have been obtained.According to the reflection characteristics of different layer boundaries of submarine acoustic wave, comparatively analyze the change of the sound intensity image of pulse signal, discuss the shallow profile data extraction method of sound intensity image based on On silt layer. Experiments show that the boundary layer division method can achieve the current range of precision drilling data. |
