In this paper, embankment or levee failure due to the interaction between a cavity within an embankment body and high water level was simulated in a centrifuge test and monitored by electrical resistivity tomography (ERT) survey technique. As the centrifuge modeling is an effective research tool for levee stability analysis and the ERT survey is generally adopted in field for health monitoring of levee, physical modeling of levee stability problem and its monitoring by the ERT survey in the centrifuge provides a great opportunity for researchers. Initially, 1 g preliminary test was performed for simulating the underground cavity using a buried ice block to ensure the simulation of such cavity in the centrifuge model. Subsequently, 20 g centrifuge test was performed. At the 20 g-level, over the three stages’ water level in river side was maintained to simulate expansion of the underground cavity with increase in groundwater level. Continuous ERT survey was simultaneously conducted to monitor the variation of internal state of the embankment body. During the final high water level, subsidence of levee surface occurred at the vertical location on top of the cavity which can lead to embankment failure. The ERT results (two dimensional contour plots) from the centrifuge test correspond well to the expected process of levee subsidence caused by upward development of inner cavity by showing definite resistivity difference between the cavity and adjacent soil. From the centrifuge test, it is concluded that the cavity within the embankment body could induce failure upon interacting with the high water level, and the ERT monitoring could effectively capture the geotechnical process which shows the upward development of underground cavity.

在本文中，在离心机测试中模拟了由于路堤体内空腔与高水位之间的相互作用而引起的路堤或堤防破坏，并通过电阻层析成像（ERT）测量技术对其进行了监控。由于离心机建模是堤防稳定性分析的有效研究工具，并且在堤防健康监测中通常采用ERT调查，堤防稳定性问题的物理建模及其通过ERT调查在离心机中的监控为研究人员提供了巨大的机会。 。最初，进行了1 g初步测试，以使用埋入式冰块模拟地下空腔，以确保在离心模型中模拟这种空腔。随后，20克进行离心测试。在20克水位时，河水在三个阶段的水位得以维持，以模拟地下洞室随地下水位的增加而膨胀。同时进行了连续的ERT调查，以监测路堤主体内部状态的变化。在最终的高水位期间，堤防表面的沉降发生在型腔顶部的垂直位置，这可能导致路堤破坏。离心试验的ERT结果（二维等高线图）通过显示空腔与相邻土壤之间的明显电阻率差异，与内部空腔向上发展引起的堤防沉降预期过程非常吻合。从离心机测试
