Abstract:

The problems, such as pavement cracking, differential settlement between bridge and roadbed, are the most important matters that engineers must be up against. The simulation of soft ground settlement is one of the difficulties. This coupled simulation of seepage and consolidation mainly uses the improved Cambridge model, depends on the software FLAC3D which is a finite difference software. As an example, the test sections’ data of an expressway in the Pearl River Delta is used for simulating soft ground settlement, the accuracy of this modeling can be validated by contrasting between the results and actual monitoring data. The result shows that the simulating numerical values and the measured data has good match, whether for the surface settlement or for the stratified settlement, it means that the simulating model can be used to reflect the soft ground settlement.

Key words: soft ground settlement, drainage consolidation by sand well, numerical simulation, FLAC3D
