“…These treatment technologies not only make the best use of natural resources, but also reduce excavated waste soil and provide high-quality fill materials. Extensive research has been conducted to explore the feasibility of solidified soil as construction fill materials [3,4]. Jamsawang et al [3] found that cementand fly ash-stabilized sediment could meet the requirement of subbase materials in terms of unconfined compressive strength and resilient modulus.…”

“…Jamsawang et al [3] found that cementand fly ash-stabilized sediment could meet the requirement of subbase materials in terms of unconfined compressive strength and resilient modulus. Niu et al [4] indicated that the shear strength of the solidified excavated soft soil increased with higher stabilizer content, and the solidified excavated soft soil exhibited excellent stability even after undergoing dry-wet cycles.…”

Most research conducted so far has primarily focused on pile-supported gravel embankments. The ability of solidified soil used as an embankment filling material has been verified, and a clear view on the performance of solidified soil embankments on piled foundations is rather limited. The three-dimensional unit cell models of pile-supported embankments are conducted to investigate the performance of solidified soil embankments in comparison to gravel embankments under static and dynamic loads. Then, a systematic parametric analysis is performed to investigate the effects of various factors, including the cohesion and friction of solidified soil, the velocity and wheel load of vehicles, the pile spacing, the height of embankments. The results show that, compared with the results of gravel embankments, the heights of the outer soil arch plane in solidified soil embankments reduces under static and dynamic loads, and the piles bear more load. In addition, the total settlements of solidified soil embankments decrease with increasing cohesions, and there is an economical cohesion of 25 kPa. The vehicle wheel load, pile spacing, and the height of embankment significantly influence the load transfer mechanism and total settlement of solidified soil embankment, while the friction angles and velocities have little effect on the total settlements and vertical stress. The relationship between the soil arch height and various parameters in solidified soil embankments is established by multiple regression analysis. This investigation highlights the advantage of solidified soil in reducing total settlement and provides an insightful understanding of the load transfer mechanism of solidified soil embankment on piled foundation.
