| Abstract: | A slope in the owner’s camp area of luoning power station is a five-grade loess slope.In order to ensure the stability of the slope and the safety of the dormitory building in front of the slope,the finite difference software FLAC3D is used to carry out numerical simulation on the step by step excavation,construction and operation of the slope,and the slope safety status is evaluated by calculating the slope deformation under different working conditions.The results show that:during the construction period,the maximum displacement of the slope is reduced from 140mm to 16mm,the anchor support has a great effect on the displacement of the slope,and the foot locking effect of the retaining wall is obvious.The field monitoring data and numerical simulation results are basically consistent,which shows that the numerical model used in this calculation is reasonable.After heavy rainfall or wet and dry cycle of rock and soil in rainy season,the displacement value of the slope does not exceed the control value,and the safety risk of the slope is under control. |
