MEANING OF PROGRESSIVE FAILURE IN BEARING CAPACITY PROBLEM OF SHALLOW FOOTING

Bearing capacity of shell strip footing on reinforced sand

In this paper, the ultimate load capacities of shell foundations on unreinforced and reinforced sand were determined by laboratory model tests. A series of loading tests were carried out on model shell footing with and without single layer of reinforcement. The tests were done for shell foundation at different shell embedment depth and subgrade density. The results were compared with those for ...

Seismic Bearing Capacity of Shallow Foundations

Influence of the Vibro Stone Column Reinforcement on The the Seismic Bearing Capacity of a Surface Shallow Footing

In difficult soil conditions, engineers sometimes choose to combine reinforced soil and spread footings instead of deep foundations. Among the available techniques for soil reinforcement, vibro stone columns are frequently used to reduce the liquefaction risk, improve the soil properties and improve the overall seismic performance. While there are different models available to evaluate the bear...

The Effect of Spatial Variability and Anisotropy of Soils on Bearing Capacity of Shallow Foundations

Naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. The main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. In t...

Bearing Capacity of Shallow Foundations on Cohesionless Soils: A Random Forest Based Approach

Determining the ultimate bearing capacity (UBC) is vital for design of shallow foundations. Recently, soft computing methods (i.e. artificial neural networks and support vector machines) have been used for this purpose. In this paper, Random Forest (RF) is utilized as a tree-based ensemble classifier for predicting the UBC of shallow foundations on cohesionless soils. The inputs of model are wi...
