This paper presents an improved earth pressure method that considers the capacity of a wall toe to carry load predict connection loads GRS segmental walls constructed with cohesionless backfills on competent foundations. In this method, response surface model (RSM) lateral coefficient replaces Coulomb active coefficient. The parameters RSM were determined from numerical studies impacts restrain...

This paper describes the laterally confined consolidation of an Israeli clay following compaction and swelling on wetting, including measurement lateral stresses. The results tests are compared to those obtained during from initially slurried condition. In comparing compression expansion indices relative vertical, mean stress, it was found that they varied, depending initial, preparation condit...

For culverts installed in soft soil, the rigid composite pile foundation is used for soil treatment, and stresses around are complicated. Centrifuge experiments numerical simulations conducted to investigate vertical earth pressures settlement over a slab culvert under high backfill foundations treated with piles. The influences of lateral length spacing on at top analysed, they have significan...

Railways are one of the largest transportation networks in world. One key subgrade problems railway track is associated with progressive shear failure (PSF). To-date, limited number studies have addressed mechanism PSF, especially extending mechanics unsaturated soils. In this paper, PSF studied aid computer program that was developed using a Visual Basic AutoCAD, Mohr-Coulomb criteria within s...
