“…Several researchers have also found that the largest tensile force occurred near the edge of the pile cap through numerical or experimental methods (Han and Gabr, 2003;Brianҫ;on and Simon, 2012;Han et al, 2012;Ariyarathne et al, 2013). However, some researchers observed that the largest tensile force of the geogrid occurred at the center of the pile cap (Zaeske, 2001;Halvordson et al, 2010;Jones et al, 2010;Van Eekelen et al, 2012a).…”

“…Experimental or numerical investigations on the structural behavior of pile-supported reinforced embankments have been conducted by many researchers (Li and Rowe, 2008;Van Eekelen et al, 2012a;Ariyarathne et al, 2013;Van Eekelen et al, 2013;Blanc et al, 2014;Lai et al, 2014;Yapage and Liyanapathirana, 2014;Rowe and Liu, 2015;Zhuang and Wang, 2015). The geogrid is considered to play an important role in improving the performance of pile-supported reinforced embankments by means of increasing the loading efficiency of the piles Huang and Han, 2009;Deb and Mohapatra, 2013;Xing et al, 2014).…”

“…Although these common GRPS foundations can improve the bearing capacity of the foundation and reduce the settlement to some extent, they are difficult to be fully developed due to the restraints of the pile and soil properties as well as the site construction conditions. For instance, the pile body bears most of the upper load in the geosynthetic-reinforced and concrete pile-supported composite foundation, but the bearing capacity of the soil around the pile cannot be easily used, which is disadvantageous to the formation of the composite foundation [6]. Although the geosyntheticreinforced and gravel pile-supported composite foundation can effectively increase bearing capacity, the large compression deformation of the pile body limits the control of the foundation settlement to some extent [7].…”

Reinforced cushion and pile are two important components of the geosynthetic-reinforced and pile-supported (GRPS) composite foundation. Studies on the traditional GRPS composite foundation with uniform section piles have compared the performance of GRPS before and after the reinforcement of cushion yet neglects the effects of reinforcement type and pile shape on this composite foundation. To address this problem, the geosynthetic-reinforced and tapered pile-supported (GRTPS) composite foundation with section-variable piles was proposed in this study as a new form of the GRPS composite foundation. The settlement of the proposed composite foundation and the stress distribution on piles and soil under three cushion conditions (gravel cushion (GC), geogrid-reinforced cushion (GGRC), and geocell-reinforced cushion (GCRC)) were analyzed through a static test by using three models of specimens with nine piles. Test results demonstrate that under the test load, the pile-soil settlement differences under GGRC and GCRC are 43.4% to 49.8% and 34.7% to 39.8% of that under GC. Meanwhile, the pile-soil stress ratios under GGRC and GCRC are 1.47 to 1.88 and 1.77 to 2.08 times of that under GC. The reinforced cushion can effectively reduce the settlement of the composite foundation and the pile-soil settlement difference, increase the pile-soil stress ratio, and relieve stress concentration in some piles. GCRC can improve the performance of the GRTPS composite foundation more effectively than GGRC under the same conditions. No negative friction region is observed on the upper piles in the GRTPS composite foundation. The tapered piles are better than the uniform section ones as well as can increase the bearing capacity and decrease the settlement of the composite foundation. The findings of this work can provide references for the engineering design and application of the GRTPS composite foundation.

“…These methods include improving the fill properties, using light-weight fill, overexcavation and replacement, pile supported, and geosynthetic reinforced (Han and Gabr 2002;Ariyarathne et al 2013). The benefits of geosynthetic reinforced embankment have been reported in several works in the references (Hufenus et al 2006;Frankowska et al 2007).…”

ABSTRACT:The behavior of the pavement is highly dependent on the deformation and stability of the underlying embankment. To optimize the design of embankment suffering heavy asymmetric traffic load in Shanxi province, China, a series of two-dimensional (2D) numerical analyses were conducted using the finite element software PLAXIS to investigate the deformation and slope stability of the unreinforced, geosynthetic reinforced, and expanded polystyrene (EPS) geofoam reinforced embankments. The results show that the general performance in the geosynthetic reinforced case is thought to be superior compared to that in the EPS geofoam reinforced case taking the slope stability into consideration. As the asymmetric traffic load increases, the embankment deformation increases significantly and obvious decrease of the slope stability safety factor is also observed. Great attention need to be paid to the influence of the heavy asymmetric traffic load.
