This paper mainly researches the structural characteristic and the stability analysis of Mahe collapse body. This paper adopts SSP (Seismic Scatter Profile) method to explore the structural characteristic of Mahe collapse body. Furthermore, this paper evaluates the stability of Mahe collapse body under three conditions by using various LEM and then calculating and comparing the safety factors of discontinuity between bedrock and coverage. Finally, this paper concludes that the geological structure of Mahe collapse body is approximately sorted into three layers.
