Soft ground improvement below bridge approach foundation using cement deep mixing columns combined with geotextile

چکیده

Vehicle load is a dynamic and embankment static load. These two types can act simultaneously to accelerate the consolidation rate of ground under embankment, which then leads differential settlement. This settlement dangerous as it cause sudden bouncing shock for vehicles on road. There are also other problems such reduction in exploitation capacity construction work due speed going through positions Lower increases waste means transport. Excessive occur from reasons improper design or construction. paper uses finite element method simulate process bridge approach calculate, check stability deformation soft this The analysis results show that without treatment quite large at 1.06 m. After reinforcement, 0.013 m, coefficient 1.032 2.739. research be applied reinforce with system cement deep mixing (CDM) columns combined geotextiles shorten time limit compensation.

Ground improvement versus hybrid foundation and deep foundation – Comparison of foundation concepts for three case histories of European significance

The focus of the keynote paper is on the comparison of different foundation concepts for three case histories of European significance. The stadium in the Austrian city of Klagenfurt was designed and built for the EURO 2008 (Austria and Switzerland) in slightly consolidated soft lacustrine clays. The shallow foundation rests on floating stone columns installed with the vibro replacement techniq...

New Technologies for Soft Ground Improvement in Japan ― Low Improvement Ratio Cement Column Method and Lightweight Banking Method

This paper presents promising new technologies for soft ground improvement which include the low improvement ratio cement column method (LCC) and the lightweight banking method using foam mixed soil (LFS). As a measure to reduce settlement and lateral deformation due to road embankment loading on soft ground, the column type deep mixing method used at a low improvement ratio of around 10-20% th...

Three-Dimensional Finite Element Modeling of Stone Column-Improved Soft Saturated Ground

Installing stone columns in the ground is an effective improvement technique to increase the load bearing capacity and reduce the consolidation settlement of the loose or weak cohesive soils. In addition to the increase in the bearing capacity and reduction in the settlement, stone columns can accelerate the dissipation rate of the excess pore water pressure generated by the surcharge, which ex...

Examination of turbulent entrainment‐mixing mechanisms using a combined approach

[1] Turbulent entrainment‐mixing mechanisms are investigated by applying a combined approach to the aircraft measurements of three drizzling and two nondrizzling stratocumulus clouds collected over the U.S. Department of Energy’s Atmospheric Radiation Measurement Southern Great Plains site during the March 2000 cloud Intensive Observation Period. Microphysical analysis shows that the inhomogene...

Seismic Performance of Square RC Bridge Columns under Combined Loading including Torsion with Low Shear

During earthquake excitations, reinforced concrete bridge columns can be subjected to a combination of axial load, shear force, flexural moments, and torsional moments. The torsional moment can be much more significant in columns of bridges that are skewed, curved, have unequal spans, or unequal column heights. Combined loading including torsion can result in complex flexural and shear failure ...
