Abstract
AbstractA full-scale test embankment reinforced with hexagonal wire mesh was constructed and monitored to evaluate its performance. The embankment was constructed with precast vertical discreet concrete panel as facing element and silty sand was selected as granular backfill material. The size of each concrete facing panel is 1.5 m × 1.5 m × 0.15 m. The embankment was founded on soft Bangkok clay reinforced by columnar inclusions. Jet grouting method was used to construct the clay-cement piles to improve the soft foundation ground. The objectives were to study and confirm the behavior of the hexagonal wire mesh reinforced embankment constructed on jet grouted cement mixing piles to improve soft ground. The observed data with analytical calculation and finite element analysis were compared in terms of surface settlements, subsurface settlements, lateral movement, excess pore pressure, and tension in hexagonal wire mesh. The analytical prediction of the surface settlements and the FEM simulation of the test embankment deformation behavior yielded good agreement with the corresponding observed data.KeywordsSoft clayReinforcementMSEDeep mixingDMM
