In this study,field and laboratory tests are used to obtain the soil conditions and mechanical properties of a 013 loess slope in Tianshui.This study introduces a hierarchical support scheme using a block stone retaining wall,and the stability of the slope is verified on the basis of the strength reduction method.Moreover,the safety factor and the equivalent plastic strain law of this slope is determined before and after application of the support using ABAQUS software in which the yield criteria of the corner point circumcircle of the Drucker-Prager(D-P)criterion is adopted.The horizontal displacement law of the slope before and after the support is also obtained using ABAQUS.The results show that using the finite element strength reduction method,the safety factor of the slope without support is 0.59;in ciontrast,the safety factor of the slope in block stone retaining wall is 1.41.Therefore,the stability state of the slope is reached.Moreover,on the basis of the finite element strength reduction method,the equivalent plastic strain zone of the slope without the stone retaining wall is located at the foot of the slope,and the failure form of the slope is local soil failure with a maximum plastic strain of 0.023.Therefore,no sliding surface is present in the slope.By comparison,an equivalent plastic strain zone occurred under the slope supported by the rock block,and the failure form of the slope is also local soil failure.In addition,the maximum plastic strain is 0.02.With further reduction of the soil strength,the upper soft soil will develop a sliding surface through the slope in the stone retaining wall.At the same time,the stone retaining wall will decrease the horizontal displacement of the soil,which can prevent the total displacement from sliding to a free surface.
