Abstract:
In recently years, the subsidence develop rapidly in Beijing. It can not be ignored the influence of the security of major project. Beijing Singapore city is located at the junction of Daxing and Hebei. The per captia water resources is 190m3.,far below the internationally safety limit 1000m3. The region is the dryland water resource and continued extraction groundwater caused land subsidence issue become increasingly prominent. With the Beijing Singapore city put into use, the amount of water shortages must further seriously and land subsidence subsidence area must be further increased. Therefore, monitor the land subsidence of Beijing Singapore city area and research its settlement mechanism, it is so important to ensure the safe operation of Beijing Singapore city . Explore the soil and water coupling mechanism of Beijing Singapore citya during land subsidence process, and optimize groundwater extraction program to ensure the safe operation of Beijing's second largest airport.
