Abstract
In this study, the stress, the bearing capacity and the settlement behavior in the loose sandy soils were investigated experimentally and theoretically. The study was performed in central loading conditions using strip and rectangular footings. The vertical stresses resulting from the external are measured for three different distances simultaneously. And also the load-settlement curves were obtained. The results showed that the bearing capacity increases when the length of the footing increases and the measured vertical stress values decrease along the depths for all the three types of the footing types. The test results were compared with theoretical results given in the literature. As seen from this comparison, the experimental results are in accordance with the theoretical results.
Highlights
Their own weight and applied external loads of the soils create stresses within the soil mass
The test results were compared with the theoretical results
Additional vertical stress values with load-settlement relationship were investigated at the five different depths inside the sandy soil
Summary
Their own weight and applied external loads of the soils create stresses within the soil mass. This stress varies depending on the severity of the applied load, soil properties and the size of the area the load is applied. Due to the soils are very complex materials, make exactly stress-deformation analysis very difficult in the soil. Theory of elasticity which is an approximate solution for the soil behavior analyses is often used. Theory of elasticity acceptances are listed as; i) soil is elastic and stress-deformation relationship is linear and ii) Soil is homogeneous.
