中文摘要：

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。

英文摘要：

Aqueduct of nuclear power plant undertakes the cooling water transportation for the nuclear power plant,it is directly related to the safe operation of nuclear power plants.On the year a number of water erosion,so its safety monitoring has a lot of significance.In this paper,aaqueduct expansion joint monitoring system is designed and implemented,and some of the data are primarily analyzed,and we draw the conclusion that the width of aqueduct expansion joint has a direct relationship with temperature.The horizontal and vertical displacements of both sides of the expansion joint are also related to the temperature,but the displacement is small.
