ADCP在内陆核电厂址水文观测中的应用

Application of ADCP in Hydrological Measuring of the Inland Site of Nuclear Power Plant

介绍了声学多普勒流速剖面仪(ADCP)的原理。以重庆涪陵核电厂为例,论证了该仪器在内陆核电厂址水文观测中的适用性;根据河流水流状况选择对应的硬件配置,可快速高效对流速、流向进行观测。总结了应用中的成功经验,提出需要注意的问题,并对利用该仪器输出数据分析计算悬沙浓度分布剖面的可行性进行了探讨。

The working principle of Acoustic Doppler Current Profiler（~） is introduced. Taking Chongqing power plant as an example, it is proved that ADCP is applicable in hydrological measuring of the inland site of nuclear power plant. The choice of the corresponding hardware configuration of ADCP can be fast and effident on the velocity, flow observation according to river flow condition. The successful experiences and the need to pay attention to the problems in the application are summed up. Using output data of the instrument, feasibility of analysis calculation of suspended sediment concentration on river profile is discussed based on the theory that the strength of acoustic return signal is directly proportional to silt concentration in water.
