摘　　要：陡河水库是一座以防洪、供水为主的大型水利枢纽,其稳定运行具有重要意义。为了分析陡河水库主坝沉降变形情况及稳定性,本文利用瑞士WILDN3精密水准仪依据精密水准法定期对坝面沉降点进行了监测。通过分析大坝高精度水准监测数据,依据大坝沉降速率图、累计沉降图及大坝稳定性判别准则,可知陡河水库主坝坝体在2007年沉降趋于稳定。Douhe reservoir is a large water conservancy project for flood protection and water supply. Its stable operation is of great significance. In order to analyze the condition of the settlement deformation and the stability of the Douhe main dam, the surface settlement points were monitored regularly by using the Swiss WILDN3 Precision Level based on Precision Leveling method. The result demonstrated that the settlement of the main dam of Douhe reservoir was tending towards stability by the year of 2007 through analyzing the high-precise leveling monitoring data, the settlement rate chart, the cumulative settlement chart and the dam stability criteria.
