埋地输油管道泄露的正演模拟研究

埋地输油管道发生泄露会造成周围土壤和地下水污染,严重威胁人民财产甚至是生命安全。文章首先研究了埋地输油管道泄露对其周围土壤孔隙度、水饱和度的影响,进而得到污染土壤的介电常数,然后利用计算机模拟不同泄漏情况下管道及其周围土壤的雷达回波,并对管道泄漏对雷达回波的影响进行分析,为提高埋地管道及其状况雷达探测数据解释有效性及探测精度提供支撑。

Research on forward modeling of buried oil pipeline leakage

The leakage of buried oil pipeline will cause pollution of the surrounding soil and groundwater, which will seriously threaten people''s property even life safety. This paper first studies the influence of buried oil pipeline leakage on the porosity and water saturation of the surrounding soil, and then obtains the dielectric constant of contaminated soil. Then the radar echo of pipeline and its surrounding soil under different leakage conditions is simulated by computer, and the influence of pipeline leakage on radar echo is analyzed.It provides support for improving the effectiveness of radar detection data interpretation and detection accuracy of buried pipelines and their conditions.
