三维高密度电阻率法在堤坝工程中的模拟试验

为检测堤坝中裂隙、洞穴及渗漏层等隐患的存在,利用三维高密度电阻率法对数字模型和物理模型建立的裂隙隐患进行探测,结果表明室内建立的物理模型在立体图和分层切片图中裂隙的形态有些变化,但其分布范围、位置与相对各自模型中实际的比例尺寸相差不大,说明数值模拟得出的结论可以为实际工程进行理论指导,具有一定的参考价值。

Simulation experiment of 3D high density resistivity method in dam engineering

In order to detect the hidden dangers in dam，like fractures，caves and leakage layers，the authors establish digital model and physical model using three-dimensional high density resistivity method． The results show that the form of fractures by indoor physical model in three-dimensional maps and slice figures have changed，but their distribution ranges，locations and actual proportions are almost same，indicating that the numerical simulation results can be a theoretical guide for engineering practice with a certain reference value．
