摘要
以上海中心城区为实验区,利用层次分析法对影响地面沉降因素的权重进行了综合分析;同时对地下水与地面沉降进行了拟合相关分析,进一步验证了地面沉降量与地下水抽取速度相关。
The center zone of Shanghai city is selected as experimental zone so as to analyze synthetically the weight of every influence factor of land subsidence and establish the predictive model of land subsidence by using hierarchial analysis method. At the same time, fitting correlation analysis is carried out towards the major factor,i. e. ground water which affects related with land subsidence. It further proves that the depth of land subsidence is related to the rate of ground water pumping.
