...Razel Ramilo; Tim Haxell; Richard Mulvad Cole This paper presents a case study on the performance evaluation of three surcharge embankments constructed on soft, compressible soils as part of the Peka Peka to Ōtaki Expressway project in New Zealand. Embankments, located near Awatea Stream and Mary...

...Merrick Jones; Richard Kelly; Shan Huang; Jinsong Huang Bayesian updating is a machine learning tool that has been used to assess the performance of an embankment constructed on soft ground, which incorporates measured data to evaluate key geotechnical parameters. The method is computationally...

...Farshad Astaraki, MD, MSc; Morteza Esmaeili, PhD An investigation was undertaken into the stability of railway embankment slopes over soft subgrades stabilised by deep-mixed columns (DMCs). Three 1 : 10 scale laboratory embankments were constructed over unreinforced and reinforced subgrade...

...Ugochukwu Nnatuanya Okonkwo For most treated soils in compacted form for earth embankments, interest had been limited to the maximum stresses they can sustain before failure. This work studied the stress–strain behaviour of a compacted lateritic soil treated with palm kernel shell ash (PKSA) from 0...

...Iman Hosseinpour, MSc, PhD; Mario Riccio, MSc, PhD; Marcio S.S. Almeida, MSc, PhD, MICE The performance of a geosynthetic-encased column (GEC) supporting an embankment is often analysed by measurement of the total deformations under the embankment, the hoop tensile force in the geosynthetic...

...Liet Chi Dang; Cong Chi Dang; Hadi Khabbaz A novel ground modification technique is proposed utilising a fibre-reinforced load-transfer platform (FRLTP) and deep cement mixing column-supported (CS) embankment constructed over soft soils. An equivalent two-dimensional finite-element model...

...Guangya Ding, PhD; Fan Sun, BE; Pengyan Dai, BE Saturated soft clay subgrade in Wenzhou was reinforced by a combination of vacuum preloading and surcharge preloading using different loading materials. Using the principle of similarity, embankments were erected on samples of the soft clay subgrade...

Cetin and Aydilek (2013) believe that the reutilisation of the FA in embankment construction can lead to several benefits lower...

...Morteza Esmaeili, PhD; Behnam Arbabi, MSEng This study investigates the role of an integrated tied back-to-back strengthening system in increasing the failure load and decreasing the crest settlement of railway embankments. The strengthening system consists of bars or tendons installed through...
