Analysis of Large-Size Flexible Shallow Foundation Settlement Basing on Foundation-Soil Interaction

Abstract:

The large-size flexible shallow foundation （LFSF） can not be designed fully in accordance with the shallow foundation design specification, for there are differences between LFSF and traditional shallow foundation. Taking the foundation project of Shenzhen Mawan port for example, considering the interaction between foundation and ground base and adopting a non-linear foundation model, the impact of foundation parameters and load conditions on basal pressure and foundation settlement were simulated to value adoption of the height-width ratio by finite element method. Analysis showed that soil physical parameters of elastic modulus, Poisson's ratio had great impacts on basal pressure and foundation settlement, and the accuracy of these parameters should be ensure in modeling. However the effects of expansion angle and cohesion were relatively small. The values of expansion angle and cohesion can refer to design specification. Foundation of this type mainly focus on flexural design.
