天津滨海新区地面沉降趋势预测

Tendency Characteristic of Ground Subsidence in Binhai,Tianjin

在分析天津市滨海新区地面沉降概况及灾害的基础上,利用天津地面沉降监测网26年的水准测量资料,采用数据拟合和多核函数方法,研究了天津滨海地区地面沉降随时间的变化规律,对滨海地区地面沉降的趋势进行预测。结果表明地面沉降这一"缓发型"的地质灾害一旦致灾,会给经济建设带来无法挽回的巨大损失。

Using the leveling data of ground subsidence monitoring network in Tianjin,the authors take the standard measuring point of all previous years elevation as the fundamental research object,use the data interpolation and the multi-kernel function,study the rule of ground subsidence in Binhai,Tianjin,and conclude the present situation and prediction of the ground subsidence in Binhai area.The result indicates the ground subsidence—a gradual geological—can bring about heavy losses once it becomes serious.
