摘　　要：通过大坝原型监测数据分析,能够了解坝体内渗压在时空上的变化趋势,在一定程度上反演出坝体、坝肩的工程质量以及防渗和排水反滤设施效果. 2010年某水库坝体和绕坝渗流监测共布置有20根测压管,经过7年多的连续观测,收集了大量的监测数据,本文通过绘制过程线图、浸润线图等方式探讨了各监测数据的时空分布规律,并结合除险加固情况、防渗墙质量检测和日常巡查状况,分析了该水库目前存在的主要问题,对今后的安全管理工作提出了合理可行的建议.The analysis of the dam prototype monitoring data can understand the change trend of the seepage pressure in the dam body in time and space,and to a certain extent,the dam body,dam abutment quality,seepage control and drainage filtration effect can be reversed.In 2010,twenty piezometric pipes were assigned for monitoring the seepage of the dam and the surrounding dam of the Junmin reservoir.After more than 7 years of continuous observation,a large amount of monitoring data was collected.In this paper,combined with reinforcement,quality inspection of cut-off wall and daily inspection status,the temporal and spatial distribution of monitoring data is discussed by drawing process line diagram and saturation map to analyze the main problems existing in the reservoir.Reasonable and feasible suggestions for future safety management are put forward.
