The landslide warning system's theory and the technology research have been the catastrophic geology important topics about the disaster prevention and reduction research. Because the technical bottleneck about the landslide's (internal inducement) dynamic information effective gathering method and suitable the technical, the massive landslide early warning method and the technical research results mainly concentrate in the catastrophe geological origin, the landslide hidden danger static investigation, the appraisal and the macroscopic forecast aspect. At present, the tendency real-time monitor, the early warning theory and computing technique's research about the catastrophe geology (mountain massif landslide) was still in the exploration and the development phase.In this paper, the mechanism of landslide and geophysical exploration methods about the investigation of landslide hazard; Under the conditions of induced polarization, the equivalent circuit model's formula was derived in detail; Focus on the geological samples' induced polarization research and physical simulation. This article is object to the slope which has obvious structural of landslide slip zone, to acquit the layer's dynamic information. Whether the frequency domain method also used the time domain method to evaluate the electrical underground medium, which is only different technical means, there is no essential difference. Geological model's induced polarization in the frequency domain and time domain can be converted with each other, but their research aims are not consistent. In frequency domain, the Cole-Cole model is relatively complex and cumbersome in the calculation. Proposed in this paper, the Cole-Cole model in time domain is relatively simple. And can simulate more appropriate to sandy clay samples induced polarization effect.The research which based on induced polarization method "the induced reactance" dynamic information gathering technology, would make the monitoring direction extend from static exploration assessment and external inducement variable to static exploration assessment and internal inducement variable, and it can realize effective real-time landslide monitoring.
