摘　　要：随着我国城市地下空间的不断发展,越来越多的临河建筑因靠近河流,场地渗透系数较大、地下水位埋藏较浅,受河水位变化影响剧烈,导致地下结构所面临的抗浮问题日益突出。以黄河南岸丁太鲁片区为研究对象,在分析该区地下水赋存条件、气候特征等自然因素以及地下水开采、水资源利用等人为因素的基础上,采用趋势分析法对地下水动态变化规律进行预测分析,提出科学合理的抗浮设防水位建议值,并对场地抗浮设防水位进行分区评价,为后期的建设规划、施工图设计提供参考。With the continuous development of the urban underground spaces in our country,more and more buildings are con-structed closer to the river,the site coefficient of permeability is large,the groundwater level is shallow,and the impact of river water level changes is significant.The buoyancy problem faced by the underground structure is increasingly prominent.There-fore,this paper presents a case history of design groundwater lever in Dingtailu area on the south bank of the Yellow River.Based on the analysis of natural factors such as groundwater conditions,climate characteristics,groundwater exploitation,wa-ter resources utilization and other factors in this area,the paper adopts Mann-Kendall trend analysis method to predict and ana-lyze the dynamic changes of groundwater,proposes the scientific and reasonable buoyancy groundwater level recommendations.The buoyancy groundwater levels of the different zone within the site are analyzed.It provides a reference for the future con-struction planning,design and construction.
