Experimental and numerical studies on footings supported on geocell reinforced sand and clay beds

Abstract: This paper presents the results of laboratory model tests and numerical studies conducted on a square footing resting on geocell reinforced sand and clay beds. Using suitable scaling considerations, a model footing size was arrived from the prototype raft foundation. Commercially available geocells made up of polyethylene having an equivalent pocket diameter of 0⋅25 m and aspect ratio of 0⋅6 were used in the experimental investigation. Clean sand was used to fill the geocell pockets in both sand and clay bed tests. Test results of unreinforced, geocell reinforced, and geocell reinforced with additional planar geogrid at the base of the geocell cases are compared separately for sand and clay beds. Results reveal that the use of geocell increases the ultimate bearing capacity of the sand bed by 2⋅4 times and clay bed by 3⋅2 times. Provision of the planar geogrid at the base of the cellular mattress arrests the surface heaving and prevents the rotational failure of the footing. Moduli of subgrade rea...

Experimental study of the effects of curing time on geotechnical properties of stabilized clay with lime and geogrid

Abstract: Lime treatment is extensively used to improve the properties of soft and weak soils One of the most important reasons for using lime is to reduce the swelling behaviour of the clay soil The react

A PSO-ANN hybrid model for predicting factor of safety of slope

Abstract: Stability analyses of slopes are routinely done to identify potential landslide sections. This is done for applying proper mitigation techniques. The stability of slopes is generally defined by using the term factor of safety (FOS). Various analytical and numerical models for calculating the value of FOS of slopes have been given by researchers. They had identified various independent parameters affecting the stability of slopes. The relation between FOS and influencing parameters is non-linear, which makes it a complex, multivariate problem. Recently intelligent systems have gained acknowledgement in solving such highly complex, multivariate problem. Artificial neural network (ANN), have got high degree success in solving such problem. However, ANN has its own limitations. Various researchers identified slow learning rate and getting trapped in local minima as the potential shortcoming of ANN. These shortcomings are associated with optimisation algorithm in the ANN. A number of metaheuristic optimisation...

Stabilization of Soft Kaolin Clay with Silica Fume and Lime

Abstract: Studies on chemically stabilised soils have shown that the effectiveness of treatment is largely dependent on the soil’s natural environment. This type of soil can be categorised as problematic due to its weak properties. At the preliminary stage, soft clay soil does not meet the requirements necessary for construction purposes because the entire load from the top of the building will be transferred to the underlying soil. This research considers the soil stabilisation of a soft clay soil (Kaolin S300) stabilised with various percentages of lime and 4% silica fume. The percentages of lime vary at 3, 5, 7 and 9%, while the percentage of silica fume is fixed at 4%. The main objective in this research is to improve the undrained shear strength of soft clay soil mixed with various percentages of lime (L) and 4% silica fume (SF). The properties of the soils were compared for kaolin only and for different percentages of lime mixed with 4% silica fume. The results showed that the optimum percentages of lime and ...

Settlements of shallow foundations on granular soil — an overview

Abstract: The main objective of this paper is to review the current state-of-the-art for predicting settlements of shallow foundations in granular soils. The traditional settlement prediction methods are critically reviewed. The Settlement '94 prediction session held in Texas clearly showed the deficiencies in the present settlement prediction methods, which generally overestimate the settlements and underestimate the allowable pressures, making the foundation designs very conservative. Some recent developments, including two deterministic methods and a probabilistic approach, are discussed as they have significant potential to improve the current state-of-the-art. Several empirical correlations relating the modulus of elasticity of soil and penetration resistances and standard penetration and cone penetration tests are summarized.
