核电站的引水渡槽承担着为核电站排放冷却水的功能,直接关系到核电站的安全运行。渡槽中常年有大量冷却水流过,不断受到侵蚀冲刷,对其进行安全监测意义重大。设计和实施了一套渡槽伸缩缝监测系统,并对其中的一些数据进行了初步分析,得出渡槽伸缩缝的宽度与气温有直接关系,伸缩缝两侧的水平位移与垂直位移也与气温有着关联,但是变化量较小。
The diversion aqueducts of nuclear power plants bear the function of discharging cooling water for nuclear power plants and are directly related to the safe operation of nuclear power plants. Aqueduct has a lot of perennial flow of cooling water, erosion by erosion, its safety monitoring is of great significance. A set of monitoring system for aqueduct expansion joints was designed and implemented. Some of the data were analyzed initially. The results showed that the width of aqueduct expansion joints was directly related to air temperature. The horizontal and vertical displacements on both sides of expansion joint were also related to air temperature Associated, but less variable.
