摘要
针对长江三角洲地区第四系松散沉积层厚度大、地下水位高、地下水量丰富、地下水动态变化幅度大等特点,利用深基坑降水抽水试验计算研究区水文地质参数,采用VisualMODFLOW三维有限差分计算软件,以上海某深基坑降水抽水试验工程为例,建立了多层含水层地下水模型,并定量评估了基坑降水引起的附加地面沉降量,为之后的结构设计与施工应对措施提供了科学依据。
Based on the hydrogeological characterristics that the quaternary loose sediments thick,high ground water level,abunant ground water,large variations of groundwater in Yangtze River Delta,the seepage calculation model is established by software Visual MODFLOW,which using the data of water pumping test in field of some foundation engineering in Shanghai as example.According to the schemes which might be applied,establish a multi-aquifer groundwater model,the additional land subsidence by dewatering is evaluated in quantity,which provide the scientific countermeasures for the design and construction in future.
