摘要
在堤坝渗漏监测中,由于影响因素复杂,资料解释存在一定的干扰。通过建立两组典型的堤坝渗漏地电模型,结合正演模拟分析其响应特征,将视电阻率拟断面图和反演结果结合分析,可以排除一些假异常干扰,提高对目标体的识别。在对某大坝的渗流异常监测中,结合实测资料拟断面图和反演结果,通过对低阻异常体的连续追踪,推断出异常渗流的原因及渗漏通道的位置,可为下一步的工程处理提供依据。
In dam leakage monitoring,due to the complexity of influencing factors,certain interference exists for data interpretation.Two groups of typical geoelectric models of dam leakage were established,and their response characteristics were analyzed by forward modeling.The combination analysis of apparent resistivity pseudo sections and inversion results can eliminate some false anomaly interference and improve the recognition of target.In the anomaly seepage monitoring of a dam,combined with the measured data and inversion results,through continuous tracking of the low resistance abnormal body,the causes of abnormal seepage and the location of the leakage passage were deduced,providing basis for engineering treatment in the next step.
