The ministry also urged motorists to take extra caution at Kanjama area along the Othaya-Kangemi section as a differential settlement on one lane rendered the road impassable.
In order to ensure that those high-speed railways can normally operate in design life, pile-supported embankments (GRPS) are widely adopted to reduce large differential settlement and postsettlement, for example, cement-fly ash-gravel (CFG) pile-supported embankments built over soft soil ground [1-4] and cementmixing (CM) pile-supported embankments built over soils of medium compressibility [5].
This finding is very important as the differential settlement may lead to cracks in the pavement.
However, a major issue for railway bridges concerns the allowable amount of differential settlement between adjacent bridge piers as this directly affect running safety, passenger comfort, and potential damage to structural components.
[16], the horizontal displacement of ground surface induced by tunneling projects can also lead to the differential settlement and cracking of existing building.
Geofoam was chosen as an alternative to conventional fills or soil modification techniques due to the underlining utilities, differential settlement potential and close proximity of wetlands.
'The weight is working out at between 300-400kg/[m.sup.3] which helps counter differential settlement and other stresses in the concrete.
Differential settlement can cause one portion of the wall to move downward while the other portion remains in place.
Among specific topics are the probabilistic analysis of finite strain consolidation with a stochastic soil compression index and hydraulic conductivity, large physical modeling to optimize the geometrical conditions of geotextile in reinforced loose sand, the ant colony optimization algorithm for the vertical alignment of highways, the non-destructive impedance spectroscopy measurement for soil characteristics, and solving the problems of differential settlement of pavement structures in the Bangkok area.
