| Abstract: | With the background of the newly built Jiangdu Airport in the middle of the Jiangsu Province,the subgrade of airport ground is treated by the surcharge preloading method and the arrangement scheme of field monitoring points is set down by aiming at the weak subgrade of coastal area and according to the subgrade settlement and stabilization requirements of airport engineering.The real time tracking observation is implemented.The article analyzes the variation law of ground surface settlement,layered settlement,pore water pressure,underground water level and lateral displacement under surcharge preloading,which can be referred for the design and study of the similar projects. |
