中文摘要:
      堤防隐患识别监测对堤防安全防洪具有重要意义。2022年汛期,辽宁省盘锦市绕阳河发生有水文记录以来的最大洪水,8月1日10时30分绕阳河下游左岸曙四联段堤防出现溃口,油田等国家重要基础设施损失严重。本文以堤防溃口隐患早期监测为目的,采用Sentinel-1雷达数据,通过小基线集合成孔径雷达差分干涉测量(Small Baseline Subset Interferometric Synthetic Aperture Radar,SBAS-InSAR)技术监测堤防沉降信息,基于层次分析法和综合指数法进行地面沉降风险分级,综合地面沉降风险和沉降发育程度构建了堤防沉降风险评价方法,并以盘锦市绕阳河堤防溃口区域为例,进行了包含堤防早期沉降监测、地面沉降风险分级、堤防沉降隐患风险分析的河湖堤防沉降隐患遥感监测评估。结果显示,2017—2022年溃口处堤防平均沉降速率为98.65 mm/a,累计沉降量达422.82 mm,低风险、中风险、高风险段堤防长度分别达13.8 km、3.5 km、2.7 km,堤防溃口位于高风险段,靠近沉降中心,存在安全隐患,可能导致堤防破坏最终引发堤防溃决。SBAS-InSAR形变监测和堤防风险等级划分在堤防溃口隐患早期监测中发挥了很好的作用,清晰地区分了各段堤防的沉降隐患大小,可以在堤防隐患早期识别中推广应用,为汛期预防和治理堤防溃决提供技术支持,为各风险区段堤防监测和管理提供参考。
英文摘要:
      The identification and monitoring of hidden dangers of levees is of great significance to the safe flood control of levees.In the flood season of 2022,the largest flood in the hydrological record occurred in the Raoyang River in Panjin City,Liaoning province.At 10:30 on August 1,the levees in the Shusilian section of the lower left bank of the Rouyang River burst,causing serious losses to important national infrastructure such as oil fields.In this paper,for the purpose of early monitoring of the hidden danger of levee breach,Sentinel-1 radar data is used to monitor the settlement information of levee through the differential interferometry technology of aperture radar integrated with small baseline.The ground settlement risk is classified based on analytic hierarchy process and comprehensive index method,and the assessment method of levee settlement risk is constructed by integrating the ground settlement risk and the development degree of settlement.The remote sensing monitoring and evaluation of river and lake dike subsidence danger is carried out,which includes early subsidence monitoring,ground subsidence risk classification and subsidence risk analysis.The results show that from 2017 to 2022,the average settlement rate of the dike at the breach is 98.65 mm/a,the cumulative settlement amount is 422.82 mm,and the length of the dike at the low risk,medium risk and high risk sections is 13.8 km,3.5 km and 2.7 km,respectively.The breach is located at the high risk section,close to the settlement center,and there are hidden dangers.It may cause levee failure and eventually levee failure.SBAS-InSAR deformation monitoring and dike risk classification play a good role in the early monitoring of dike breach hazards,clearly distinguish the size of the settlement hazards of each section of dike,and can be popularized and applied in the early identification of dike hazards,providing technical support for the prevention and control of dike breach during flood season,and providing references for the monitoring and management of dike in various risk sections.
