“…Most of previous studies have investigated the behavior of conventional piles under pure horizontal loads. Only a limited number of studies have investigated the response of conventional piles subjected to inclined loading using physical modelling under single gravity [8][9][10][11][12][13] or multiple gravities [14] and field-scale tests [15][16][17]. Early studies, using physical model, presented by Jain et al [8] and Lee et al [9,10] suggested an increase in pile head horizontal displacement in the presence of axial loading.…”

“…So, numerical methods come to the rescue. In particular, in the works [18][19][20] it was investigated the problems of formation and development of plastic deformation areas in the homogeneous base, taking into account the rigidity of the foundation and the above-foundation structure. It was noted that areas of plastic deformations under the stamp thickness H begin to form not only under its edges, but also in the depth of the core under its base.…”

The task of this research is to determine the values of the generalized strength parameters of the foundation soil and , at which the depth D Z of the development of Coulomb areas of plastic deformation under the edges of the foundation of finite rigidity thickness Н , loaded with a uniformly distributed load of variable intensity q and foundation of the same thickness, bearing a rigid above-foundation structure of variable height H * will correspond to the closure of plastic area under the base of the foundation what is complied with the ultimate state of the foundation (according to Prandtl). To carry out computer modeling a list of variables of design parameters that influence the process of formation and development of plastic areas under the sole of the foundation, and the intervals of their change, has been established. As a result of the calculations and processing of the data obtained it was found that the numerical values of and differ significantly from each other: equations of approximating curves of dependencies of the form have different forms correspondingly and are described by the different approximating expressions. If it is given the values of the generalized strength parameters of the foundation soil and , which the soil mass should have after its fixing, then using the graphs shown in Fig. 6-10 and the table it will be possible to conclude whether the limit state of the fixed soil base will be achieved under given loads. In other words, focusing on the numerical values of and , it is possible to determine the values , which must be obtained in the process of fixing the soil base so that the specified external load does not exceed the maximum permissible value.

“…Many researchers studied the shallow and pile foundation system on different soil profiles and conditions. Several studies have been modeled all kinds of problems of the foundation system by numerical solutions (Bartolomei, & Omel'chak, 2003;Bowles, 1996;Burd, & Frydman, 1997;Burland, 1995;Huang, Jiu, Jiang, & Lie, 2017;Katzenbach, Arslan, & Moormann, 2000;Maharaj, & Gill, 2017;Mali, & Singh, 2018;Michalowski, & Shi, 1995;Oh, Hunag, Surarak, Adamec, & Balasurbamaniam, 2008;Oh, Lin, Bui, Huang, Surarak, & Balasurbamaniam, 2009;Potts, & Zdravkovic, 2001;Poulos, Small, & Chow, 2011;Prakoso, & Kulhawy, 2001;Roh, Kim, Kim, 2019;Shahriar, Sivakugan, & Das, 2012;Wulandari, 2013). Prakoso, & Kulhawy (2001) studied the effects of raft width and pile depth on the raft piled foundation.…”

“…The result indicated that the ratio of pile group to raft width and pile depth are the crucial elements. Bartolomei, & Omel'chak (2003) studied the effect of loading character on the analysis of pile settlements. They showed that if the soil where the piles locate is of high plasticity clay, the amount of settlement at the same load level will be higher than that of low plasticity medium-hard clay.…”

In this study, the foundation systems of a structure on different soil profiles and different groundwater levels are modeled and analyzed. Several difficulties encounter during the basic design and implementation phases. In particular, the high groundwater level, the load on the soil under the load-bearing capacity, liquefaction causes many problems such as emergence. Within the scope of this study, foundation systems which based on six different soil profiles with a high groundwater level modeled with Plaxis 2D program. Thus, the stress and displacement conditions of the soil about the foundation system as a result of the soil properties and groundwater level changes in problematic soils investigated.
