Earth embankments are often required at construction sites to support roads, networks, and rail systems. Therefore, this paper studies different methods for improving soft soil in order to construct an earth embankment on such soft soil. A numerical analysis was performed using 2D finite element software (Plaxis) to simulate the proposed embankment and the underlying soil. The findings revealed that the soil at the site could not sustain the stresses imposed from the full height of the embankment, leading to shear failure in the soil before establishing the proposed height of the embankment. To tackle this problem, two techniques were considered and a comparative analysis was conducted to assess the effectiveness of these techniques. The first technique involved using lightweight materials, such as soil mixed with sawdust or geo-foam for constructing the embankment. In the second technique variety of replacement techniques, including concrete piles (CP), deep-mixing columns(DMC), stone columns(SC), and sand piles(SP) were employed to improve the bearing capacity of the soft soil layers. Research findings indicate that only 60% of embankment height could be constructed on non-improved soil with acceptable settlement. Using lightweight materials significantly reduces settlement and stress without the need for additional improvement measures. Replacing the weak soil with different materials enhances the soil properties and helps in transferring loads through the soil. Replacing soft soil reduced the settlement by ratio varied between 8.50–75% and the stress by ratios ranging from 30–80%. Importantly, the findings from DMC align with those of CP. Finally, British Standard 8006 (2010) overestimates the loads acting on CP by a ratio varied from 2 to 14. This ratio increases as the pile's material stiffness decreases.

“…DSM is an in situ ground improvement technique that enhances the parameters of a weak subsoil by introducing a hydraulic binder into its structure, e.g., lime [8][9][10], cement [11][12][13][14][15][16], fly ashes [17][18][19][20], or a combination of different types of binders and activators [21][22][23]. It must be noticed here that the issue of this study is very much related to the production of backfill materials for the mining industry.…”

This paper presents the results of laboratory testing of samples obtained from soil–cement composite columns produced on a real-world test site as part of a research and development project. The introduction presents the motivation of the research and the goals that guided the layout of a research program. The general geotechnical conditions, initially assumed methodology of soil–cement composite sampling, and finally, the methodology of strength tests were presented. In tests conducted with the measurement of the strain-stress path, the strength and stiffness of the material were determined in various modes of the stress–strain path, including unloading/reloading cycles. The test results were presented in the form of graphs presenting soil–cement composite stiffness in the function of material strength and subjected to a short critical discussion against the background of reference samples from composites prepared in laboratory conditions. This allowed for their qualitative and quantitative assessment and the formulation of conclusions and guidelines, concerning the execution of works and especially the potential practical outcomes (benefits for numerical modeling), juxtaposed in the summary. Some prospects and needs for future developments were also formulated on the basis of actual experience.

improvement, the effectiveness of treatments and the performance of ground-improved structures. Accordingly, the issue is organized by subdividing papers into two sections, the first one dealing with new technologies ( 8), the second one focusing on applications (5).We, as guest editors, wish to thank the editorial board of Geotechnical and Geological Engineering for giving this opportunity and for the expert assistance provided throughout the publication process. Simultaneously we hope that readers will find this special issue on Novel Technologies for Grouting, Jet Grouting and Soil Deep Mixing useful and stimulating.
