摘　　要：该文以徐州市西北部重点沉降区作为研究区域,布设精密水准沉降监测网,进行定期观测,并进行严密数据处理,获取该地区地面沉降监测结果。监测结果表明,研究区域在监测周期内的最大沉降速率为62 mm/年,位于丰县凤城街道。将沉降值进行插值拟合后,统计地面沉降速率超过10 mm/年的沉降区面积为2185 km2,占研究区域总面积的67.1%。相关监测结果可为该地区地面沉降灾害防治及城市建设决策分析提供精确依据,并为类似工作及研究提供参考。Using the key subsidence area in northwest Xuzhou as the study area,a precision level subsidence monitoring network was deployed,regular observations were made and rigorous data processing was carried out to obtain the ground subsidence monitoring results for the area.The monitoring results show that the maximum subsidence rate in the study area during the monitoring cycle is 62 mm/year,located in Fengcheng Street,Feng County.After interpolation and fitting of the subsidence values,the subsidence area with a ground settlement rate exceeding 10 mm/year was calculated to be 2185 km~2,accounting for 67.1%of the total area of the study area.The relevant monitoring results can provide an accurate basis for ground settlement disaster prevention and control and urban construction decision analysis in the area,and provide a reference for similar work and research.
