- Abstract:
- To study the stability problem of high filling digging deeply embankment slope resulted from heavy rain, the instablility mechanism of debris slope caused by heavy rain is analyzed. Under two calculation operating conditions, as is heavy rain and normal operating condition, the stability of slope is calculated. The Morgenstern-Price Method is adopted, and the change of the strength, ability of shear strength and safety factor of slope are analyzed. Compared with the calculated rusults under nomal operating condition, under the heavy rain operating condition, the strength and ability of shear strength is much lowed, and the safety factor is much reduced. So heavy rain lows obviously the strength and ability of shear strength and reduces the safety factor, so to result in the slope being collapsed. So it provides evidience for analysis deformations stability assessment and control of high filling digging deeply embankment.
