摘要
河道底部的障碍物会影响河道航运的正常运行,并对往来船舶的安全行驶造成潜在危险。以某河道水闸拆除后遗留的建筑基础为研究对象,通过采集该河道水闸基础的水上并行电法数据,对比水闸建筑基础与河道背景地层之间的电性差异,研究了并行电法在河道工作环境中的探测效果,并通过建立河道水闸建筑基础的电阻率正演模型,对比分析了正演结果与实际探测结果的区别,进而得出了水闸建筑基础的空间位置及大致形态,证明了并行电法在河道水闸建筑基础探测中具有较好的应用效果。而对于多条水上并行电法测线能否获得水下建筑物更为详细的电性特征及三维轮廓,以及水下建筑物的外部形状是否会对并行电法的异常响应特征存在明显影响的问题还有待研究。
The obstacles at the bottom of the river will affect the normal operation of the river navigation,and will cause potential danger to the safe driving of ships.Taking the building foundation left behind after the demolition of a river sluice as the research object,this paper collects the data of parallel electrical method over river that is the river sluice foundation and compares the electrical difference between the sluice building foundation and the river background stratum.The detection effect of parallel electrical method in the river working environment is studied.By establishing the resistivity forward modeling of the river sluice building foundation,the difference between the forward modeling results and the actual detection results is compared and analyzed Then,the spatial location and general shape of the sluice building foundation are detected,which proves that parallel electrical method has good application effect in the detection of the sluice building foundation.The question is whether the more detailed electrical characteristics and three-dimensional contours of underwater buildings can be obtained from multiple water parallel electrical survey lines,and whether the external shape of the underwater buildings will have a significant impact on the abnormal response characteristics of the parallel electrical method is still to be studied.
