混凝土面板堆石坝施工期的内部沉降观测可通过水管式沉降仪来实现，实时观测数据可用来指导大坝的施工进度和质量控制。以新疆吉勒布拉克水电站混凝土面板拦河大坝为例，介绍水管式沉降仪沉降测点的布置情况，阐述测点基准值的选择及技术指标的要求，根据观测数据，从相同高程处、同一观测断面处、不同沉降时间等几方面分析沉降规律，进行误差分析，并与国内外其他工程进行比较，分析统计结果说明，堆石坝施工期的内部沉降符合一般规律。

Inside settlement observation of concrete block rockfill dam during construction period can be done by hydraulic overflow settlement gauge. Real-time observation data can be used to guide the dam's construction schedule and quality control. Taking Xinjiang Gilles Braque hydropower station concrete block rockfill dam as an example, it introduces measuring point arrangement of the gauge, describes the selection of reference value and the requirement of technical index of measuring point. According to the observed data, it analyses settlement rule from several aspects, such as the same height, the same observation section, different settling time. It carries out the error analysis, and compares with other projects at home and abroad. The statistical analysis results show that inside settlement of the rockfill dam during construction period is accordance with general rules.
