Ground Reaction of Lightly Overconsolidated Subsoil in Reinforced Piled Embankment under Cyclic Loads

Subsoil support is generally ignored in the design of reinforced piled embankments, resulting a very conservative for settlement control. This philosophy may lead to an unnecessary increase construction costs, especially embankments constructed over subsoil medium and high compressibility (i.e., compression index larger than 0.2). paper presents ground reaction lightly overconsolidated embankment subjected cyclic loads purpose investigating general behavior subsoil, it promotes sustainable development technology. The under both static was comprehensively analyzed terms incremental vertical stress, which exhibited approximately same profile. However, load 23% that load. A parametric study then performed loads, results showed stress carried by most sensitive pile spacing amongst all parameters considered this paper. analysis demonstrated 88% when enlarged from 2.0 3.0 m. Finally, modified analytical method presented, reasonable agreement with numerical simulation, particularly relatively low geogrid stiffnesses, height (<6.5 m), small (e.g., 2–3 m center center).
