摘要
通过近十五年的地表沉降观测,分析了天津滨海地区地面沉降的机理,浅层欠固结软土的排水固结及深层粘性土释水压缩对地面沉降的影响;通过现场水文地质资料的勘察和室内试验,计算了地下水位的下降对地面沉降的影响;提出了控制地面沉降的措施。
The mechanism of the land subsidence in Tianjin Binhai New Area was analysed according to the observation about 15 years.The land subsidence was influenced by the shallow underconsolidated soft soil＇s drainage solidifying and in-depth soil moisture release compression.The influence of the ground water levels fall to the ground subsidence was calculated and surface subsidence control measures were put according the exploring of on-site hydrogeology information and laboratory experiment.
