摘要
本文采用充电法、自然电场法、探地雷达和高密度电法等物探方法查明了某水库堤坝渗漏通道的空间分布情况。通过充电法、自然电场法圈定渗漏带的平面分布情况;再通过探地雷达和高密度电法查证坝体渗漏通道的规模、深度及附近坝体是否存在裂缝和松软层。结合各方法成果综合分析大坝坝体的质量及潜在隐患,为后期维护加固设计工作提供物探资料。
The spatial distribution of leakage channels of studied reservoir dam was effectively identified through the charging method, natural electric field method, ground penetrating radar and high-density electric method. Charging method and natural electric field method were selected to examine plane distribution of leakage channels. Ground penetrating radar and high-density electric method were used to determine the scale and depth of the leakage channel of the dam body and whether there are cracks and soft layers near the dam body. Combined with the results of various methods, the quality and potential hidden dangers of the dam body were comprehensively analyzed, which provided geophysical exploration results for the later maintenance and reinforcement design work.
