Discussion on the Design Buoyancy Ground water Level in Dingtailu Area of Jinan
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 ground water 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.
