Study on Post-Construction Settlement of Ningbo Airport Runways
Built on soft soil foundation, the runways settlement of Ningbo Airport has been observed since operation. Through observations respectively after one and nine years in service, we find that the post-construction settlement is directly related to the soft layer thickness and the sand drain depth; meanwhile the accumulated impact caused by landings of aircrafts is yet another factor which cannot be neglected. Post-construction settlement mostly occurs in the initial operation stage of the airport. The maximum cumulative post-construction settlement is 12.95cm one year after operation and increases to 23.70cm nine years after, which is far beyond the design value 8cm. The differential settlement is less than 4cm one year after operation, and stays below 4cm nine years after except for a few points, which basically meets the design requirements.
