Extraction of Channel Silt Layer by Shallow Detection Data and Program Implementation

针对近海航道淤泥沉积现象严重,淤积量对航道安全通行造成威胁的问题进行研究.实验设备采用具有穿透性强、效率高等特点的浅地层剖面仪.仪器测量的原始数据通过MATLAB编写程序算法代码,通过波形特征算法,自动提取淤泥层界数据,并通过中值滤波的方法将异常误差数据值剔除.通过比对已有柱状样数据,表明该算法提取淤泥层界精度满足施工要求.

In view of the serious silt deposition in the offshore channel,the problem of the threat of the silt amount to the safe passage of the channel is studied.The experimental equipment adopts a shallow layer profiler with strong penetrability and high efficiency.The original data of instrument measurement is programmed by MATLAB,and the boundary data of sludge layer is automatically extracted through wave feature algorithm,and the abnormal error data value is eliminated by median filtering.By comparing the data of the existing columnar sample,it is shown that the precision of the algorithm is satisfied with the construction requirements.
