Australia’s first trains designed 200 km/h are being delivered to Western Australia for the TransWA country rail system (Hammond, 2003). The construction of a railroad structure in soft clays in itself is a significant cost, and many design problems are caused by the requirements
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, sto
Recent Developments in Ground Improvement Techniques - A Review
In recent years rapid development of infrastructures in metro cities compounded with scarcity of useful land and compelled the engineers to improve the properties of soil to bear the load transferred by the infrastructure e.g Buildings, bridges, roadways railways etc. The enginee
Seismic performance of group pile foundation with ground improvement during liquefaction
A pile foundation with ground improvement under the footing is a composite objectives of enhancing seismic performance and rationalizing substructure by combining improvement. Although effectiveness this method has been confirmed in previous studies for application to soft ground
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 emba
Numerical Analysis on Performance of the Middle-Pressure Jet Grouting Method for Ground Improvement
This study focused on the middle-pressure jet grouting method, which has a complicated development mechanism for columnar soil-improved body, with aim of establishing computer-aided engineering (CAE) system that can simulate performance computer. Furthermore, in order to confirm
Ground improvement versus hybrid foundation and deep foundation: three case histories of European significance Amélioration du sol contre fondation hybride et fondation profonde: trois cas d’importance européenne
The focus of this invited 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 EURO 2008 (Austria and Switzerland) in slightly consolidated soft lac
settlement analysis considerng sand mat induced initial settlement in soft ground improved by pbd
the ground improvement using plastic board drain (pbd) in soft soil was undertaken by sand mat formation, pbd installation, preloading surcharge, and removal of surcharge. during this procedure, the sand mat formation induced an initial settlement. however, it was very difficult
Tests Research on Grouting Materials of Waste-Concrete-Powder Cement for Goaf Ground Improvement
Waste concrete powder (WCP) is proposed to replace part of the cement seek environmentally friendly grouting materials for ground improvement in mine goaf. The optimal mixing proportion was selected based on performance indexes water-separation ratio, stone rate, viscosity, setti
Enhancing Ground Improvement of Dredging Landfill in South Korea’s Western Coastal Region: Insights into Dynamic Compaction Characteristics
In this study, a dynamic compaction soil box test is performed to analyze the effect of changes in energy according pounder tamping number compactions on ground improvement. As reproducing situ challenging, 3.0 m × 2.4 1.0 used. The repetitions tested up six steps, five times at
