Abstract

Abstract

Subsidence predictions of reclaimed airports on soft soil foundation is an important issue for airport construction. Based on an airport under construction in Xiamen,the subsidence and average consolidation degrees of soft soil foundation during the preloading period were studied by the measured curve fitting method,finite element analysis method and theoretical calculation method,and the consolidation degree of the current airport foundation was estimated. The results showed that:the subsidence and consolidation degrees calculated by the three methods were in few different,which could well explain the preloading effect of the airport foundation of being preloaded; the calculation results of the three methods were comparatively consonant with the measured results, and the three results could be compared with each other to study the law of subsidence evolution in soft soil areas; the average consolidation degree of the airport construction area subjected to the preloading loads of the last stage had exceeded 90%,and the main consolidation had completed.
- subsidence,
- soft ground,
- airport,
