摘　　要：利用1985-2015年天津滨海新区一等水准测量数据,对水准点高程变化进行了拟合计算。在建立地面高程模型的基础上,计算得到了滨海新区的低地面积现状,分析了地面沉降发展过程与特点,为地面沉降防控提供技术支持。High-quality leveling data of the Tianjin Binhai New Area from 1985–2015 are used to calculate the height change of leveling points through fitting,and establish a model of ground elevation.This model is then used to calculate the extent of lowland areas in the Binhai New Area and analyze the development process and characteristics of land subsidence in the region.The results of this study provide technical support for land subsidence prevention and control.

关 键 词：水准测量 高程模型 拟合计算 地面沉降 过程分析
