Study of bearing capacity of strip footing resting on reinforced sand
نویسندگان
چکیده
This research was performed to investigate the behavior of strip footing on geosynthetic reinforced sandy soil and to study the effect of different parameters contributing to their performance using laboratory model tests. The parameters investigated in the study included top layer spacing (u), width of reinforcement (b), vertical spacing between layers (s) and number of reinforcement layers (N). The test was performed on a mild steel tank having dimensions of 1.5 m × 1.5 m × 0.6 m and plate having size 30 cm × 90 cm × 2.5 cm. Test results shows that the optimum depth of reinforcement is 0.6B and the optimum width of reinforcement layer is 3B. The best spacing between geogrid layers which gives higher bearing capacity is at 0.4B and effective number of layers obtained as 3.

Seismic Bearing Capacity of Strip Footings on Pile-Stabilized Slopes
This paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. The resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. This comparison indicates an acceptable agreement. The variants of the study incl...

This paper presents the results of a series of small-scale model tests and numerical analyses conducted on circular and ring model footings located near geogrid reinforced sand slopes. Layers of geogrid were used as reinforcement. For numerical analyses Finite Element Method (FEM) was used. The effects of reinforcement depth, size, number of layers, and the horizontal distance between reinforce...
متن کاملBehavior of Model Circular Footings on Silty Soils with Cellular Supports
An experimental study of the effect of silt and influence of cell confinement on the bearing capacity of circular footings on silty sand was carried out. Laboratory experiments on clean sand and sand containing silt up to 25 % were performed. Cells with different heights and diameters were used to confine the silty sand. The effect of proportion of silt in sand, cell diameter, cell height and t...
متن کاملNumerical and physical modeling of soft soil slope stabilized with stone columns
There can be many reasons for engineers to place the footings near a slope such as leakage of suitable sites or architectural considerations. One of the approaches to increase the amount of bearing capacity, especially in soft soils, is adding stone columns to the soil. In this research, the behavior of a strip footing placed near a stone column reinforced clayey slope was investigated. For thi...
