摘要
测压孔是监测坝基扬压力的主要方法之一,测压孔的工作状态对获取可靠的坝基扬压力监测资料和评价大坝安全具有重要意义。以华安水电站坝基测压孔工作状态评价为例,分析了测压孔工作状态评价的基本内容和主要方法,提出了测压孔主要评价指标的评价标准和测压孔工作状态的分类方法,为测压孔工作状态评价提供了系统的参考依据和工程经验。
Piezometric hole is a main way for monitoring uplift pressure on dam foundation,and its working status is important to get the reliable monitoring data of uplift pressure and to assess dam safety.In this paper,taking the working status evaluation of piezometric hole in Hua-An Hydropower Station as an example,basic contents and main methods are analyzed on the working status evaluation of piezometric hole,and the standards of main evaluation index and the classification of piezometric hole working status are proposed.The research results can provide reference and experience for evaluating the working status of piezometric hole.
