摘　　要：通过在水库坡体设置表面监测点和深部监测点,对其变形规律和变形趋势进行综合分析。研究结果表明:表面监测中,边坡X向、Y向与H向变形表现出开挖期坡体变形量分别占各方向总变形量中的60%、80%、80%;在X向中累计位移量最大值为106.20 mm;垂直方向上的位移累计值在60 mm之内,位移累计值最大达到了58.60 mm,三个方向上的变形在一年之后有小幅度的上升,变形速度减弱,截止至今,均保持稳定;深部监测中,平洞监测点在水平方向和垂直方向上的位移在前期增长速度较大,在后期基本保持稳定,变形量较小。垂直方向最大沉降点在深部拉裂缝f44-5、SL44-3、SL44-1之间,这说明深部变形主要受到深部拉裂缝的控制。In this paper, by setting surface monitoring points and deep monitoring points on the slope, the deformation law and deformation trend are comprehensively analyzed. The research results show that: in the surface monitoring, the deformation of slope in X-direction,Y-direction and H-direction shows that the deformation of slope in excavation period accounts for 60%, 80% and 80% of the total deformation in each direction respectively;the maximum accumulated displacement in X-direction is 106.20 mm;the accumulated value of displacement in vertical direction is within 60 mm, and the maximum accumulated value of displacement reaches 58.60 mm, the deformation in three directions after one year There is a small increase in the deformation in the three directions after one year, and the deformation rate is weakened, and up to now, they all remain stable;in the deep monitoring, the displacement in the horizontal and vertical directions of the flat cave monitoring point has a larger growth rate in the early stage, but basically remains stable in the later stage, and the deformation amount is small. The maximum settlement points in vertical direction are between deep pulling cracks f44-5, SL44-3 and SL44-1, which indicates that the deep deformation is mainly controlled by deep pulling cracks.
