摘　　要：结合前方交会与测斜仪两种位移值,整体评价柘溪进水口边坡的稳定性。虽然边坡地表位移有明显的趋势性,但位移主要发生在地表至地下5m深度,且没有加速下滑迹象,最大月均位移仅0.3mm,满足安全控制标准,表明边坡目前是稳定的。通过对比两种位移观测数据,得到了测斜位移的实际测量精度为5~10mm,仅依据测斜数据作短期位移定量分析应考虑测量误差的影响。Combining with the two kinds of displacements obtained by the inclinometer and forward intersection,the overall stability of the intake slope of Zhexi hydroelectric power station is evaluated.Although the displacement of the slope surface has obvious trend,but the displacement occurs mainly at the surface down to 5m depth,and there is no evidence of acceleration. The maximum monthly average displacement is only 0. 3mm and meets the designed safety standards,which indicates that the slope is stable at present. By comparing the two kinds of displacement observations,we can find that the actual measurement accuracy of the inclinometer displacement is from 5 to 10 mm. Based only on inclinometer data to do the quantitative analysis of the short-term displacement,the effects of errors in the measurements should be considered.
