BACKGROUND The method of characteristics (also called as the slip-line method) is used to calculate the bearing capacity of strip footings on ponderable soil. The soil is assumed to be a rigid plastic that conforms to the Mohr-Coulomb criterion. The solution procedures proposed in this paper is implemented using a finite difference method and suitable for both smooth and rough footings. By acco...
the problem of a footing on slope is encountered regularly in engineering practice, with some noteworthy examples being bridge abutments and basement excavations. in this paper, the bearing capacity of a footing replaced near a slope crest was studied. model tests were carried out using square model footing of 100 mm width. a tank 0.3 m deep, 0.6 m wide, and 0.9 m long was used for the model be...
stability of foundations near slopes is one of the important and complicated problems in geotechnical engineering, which has been investigated by various methods such as limit equilibrium, limit analysis, slip-line, finite element and discrete element. the complexity of this problem is resulted from the combination of two probable failures: foundation failure and overall slope failure. the curr...
soil slopes are sometimes curved in plan rather than being straight. this curvature,especially when it is convex, decreases the bearing capacity of the slope. finite element methodhas been used here in this research to investigate the reducing effect of curvature on bearingcapacity of a slope. failure of soil has been assumed to be according to mohr-coulomb criteria;but the flow rule of the soi...
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...
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...
In this study, various machine learning algorithms, including the minimax probability regression (MPMR), functional network (FN), convolutional neural (CNN), recurrent (RNN), and group method of data handling (GMDH) models, are proposed for estimation seismic bearing capacity factor (Nc) strip footings on sloping ground under events. To train test model, a total 1296 samples were numerically ob...
