摘要
田湾核电站是目前全球在运和在建总装机容量最大的核电基地,对于保障江苏省及华东地区的能源安全具有重要意义。核电站属于重要基础设施,其形变大小将直接威胁核电站的安全运营。文章采用小基线集雷达干涉测量(SBAS-InSAR)技术,利用2021年1月—2023年12月的96期Sentinel-1A影像,首次获取了田湾核电站的详细形变信息。结果表明:已建成的1~6号机组区域建筑物及地表均稳定,无明显形变发生,形变速率范围为-3~3 mm/a;正在施工的7号、8号机组西侧的砂石堆积场存在较严重形变,最大沉降速率可达50 mm/a;核电站西南部不锈钢车间和库房区域存在较大形变,荷载过大可能是该区域形变较大的主要原因。相关管理部门需高度关注西南部形变较大区域,并采取相应的防控措施。
Tianwan nuclear power plant is the nuclear power base with the largest total installed capacity in operation and under construction in the world,which is of great significance to ensure the energy security of Jiangsu province and east China.Nuclear power plant is an important infrastructure,and its ground deformation will directly threaten the safe operation of nuclear power plant.In this paper,the small baseline subset interferometric synthetic aperture radar(SBAS-InSAR)technique is applied to obtain the detailed deformation of Tianwan nuclear power plant for the first time with 96 Sentinel-1A images from January 2021 to December 2023.The results show that:the buildings and surface of unit 1~6 are stable,there is no obvious deformation,and the deformation rate ranges from-3 mm to 3 mm;there is serious deformation in the sand and gravel storage site on the west side of unit 7 and unit 8 under construction,and the maximum subsidence rate can reach 50 mm/a;there is a large deformation in the stainless-steel workshop and warehouse area in the southwest of the nuclear power plant,and the excessive load may be the main reason for the large deformation in this area.The relevant management departments should pay close attention to the large deformation areas in the southwest and take corresponding prevention and control measures.
