摘要
为探究高密度电法在高含盐量海塘堤防隐患探测的适用性,以杭州湾北岸某段高含盐量海塘堤防为研究对象,应用多功能全波形直流电法仪开展系统探测。高盐环境显著降低堤身土体电阻率,但高密度电法测量的视电阻率反演模型仍能清晰划分结构层,层间分辨效果较好,可有效探明堤身土体结构状况、管涵埋设位置、管周填土密实度差异及地下水位等。高密度电法在高盐海塘堤防隐患探测中具有工程适用性。
To investigate the applicability of the high-density electrical resistivity method in detecting hidden dangers in high-salinity seawall embankments,this paper selected a section of high-salinity seawall embankment on the northern coast of Hangzhou Bay as the research subject.Systematic detection was conducted using a multifunctional full-waveform direct current electrical method instrument.The results showed that although the high-salt environment significantly reduced the soil resistivity of the embankment,the apparent resistivity inversion model obtained from the high-density electrical resistivity method can still clearly delineate structural layers with effective interlayer resolution.This enabled the detection and localization of the embankment soil's structural conditions,burial locations of pipe culverts,differences in the compactness of backfill soil around the pipes,and groundwater levels.The high-density electrical resistivity method demonstrated engineering applicability in detecting hazards in high-salinity seawall embankments.
