为监测卡马水电站水工建筑物基础的工作状态,在混凝土建筑物的基础中、土坝的坝体和基础中埋设了测压管。由于施工草率和设计偏差,50％测压管失败了。在运行期间,重新建立了测压管网,现计有393支。在运行的头几年,采用轻便式弹簧压力计测量,其准确度很差。1957～1960年间,在测压管上安装了水银压力计,测量精度明显提高,并消除了弹簧压力计的全部缺点。1974～1976年间,在17个有水银压力
In order to monitor the working status of the foundation of hydraulic structures in Kama Hydropower Station, piezometric tubes are embedded in the foundation and foundation of the concrete dam. 50% pressure tube failed due to construction sloppy and design deviations. During operation, a new manometry network was rebuilt and there are now 393 pressure gauges. In the first few years of operation, portable spring pressure gauges were used to measure accuracy, which was poor. Between 1957 and 1960, a mercury manometer was installed on the manometer to improve the measurement accuracy and eliminate all the disadvantages of the spring manometer. Between 1974 and 1976, 17 had mercury pressure
