Abstract: Based on comprehensive qualitative analysis of monitoring data of Qingxi dam foundation uplift pressure, statistical models of dam foundation uplift pressure were established, components of typical years' variation were separated.Further more, changes of monitoring items and influencing factors were analyzed.Therefore comprehensive analysis and evaluation of varying state of uplift pressure are made.

摘要： 在对青溪大坝扬压力的监测资料进行全面的定性分析基础上, 建立坝基扬压力统计模型, 分离出典型年年变幅中的各个分量, 定量分析各监测量的变化规律及影响因素, 由此对坝基扬压力的变化状态进行了综合分析和评价。
