The Stability Evaluation of the Landslide in the Northwest Sit of Certain a Substation

Article Preview

Abstract:

The landslide which located in the northwest of the transformer substation was studied and the evaluation of the stability was contained.Through analyzing the regional geological conditions and landslide engineering conditions, summary of the reason of the landslide was made. Based on two-dimensional rigid body limit equilibrium theory, residual thrust method was used in calculation. Through the researching of the landslide, some factors that play important role were found. According to the investigation report, select the main slip profile as the basis for calculating. Combining with soil C&φ, the value of the inversion parameters can be got. Calculation process contained two engineering conditions. In the natural condition, the landslide is stable, and in the rainstorm condition, the landslide is not stable.
