Physical simulation study of natural electric field in landslides
In order to clarify the response law of rock and soil types,moisture content,and slope angle in natural potential method moni-toring before landslide occurrence,the variation characteristics of natural potential curves during simulated landslide under the action of various factors were studied.By analyzing the comprehensive influence of single factor and multiple factors,the natural potential re-sponse law of landslides before and after landslide occurrence was summarized under experimental conditions.The results show that when using the natural potential method to predict landslides,it is not related to its natural potential value,but only to the rate of natural potential change.Different rock and soil types and slope angles will cause an increase in the natural potential signal value before land-slides occur,and the higher the rate of increase,the higher the severity of landslides.The natural potential signal value will decrease be-fore the landslide occurs in experiments with different water contents,and the faster the natural potential signal decreases before sliding,the higher the severity of the landslide.
