“…From the literature, the use of twodimensional is the choice of many researchers in the study of embankment stability. Plaxis [81], Abaqus [82] and Fast Lagrangian Analysis of Continua (FLAC) [83] are the types of software used for analysis, testing, and design in geotechnical engineering. However, the use of FLAC is less common in the study of the road embankment.…”

“…The elimination of pore water pressure increases soil strength, which would enable it to sustain the load. Da Silva et al [81] studied the impact of PVDs installation on stability and embankment settlement. Using back-analysis to find sufficient material model and calculation of values using elastic-viscoplastic (EVP) through FEM to four dikes on very soft clay, it was found that PVDs very significantly accelerated settlement and increased FoS.…”

This paper presents an exhaustive review of the challenges faced in the construction of road embankments on soft ground and proposes a direction for future development. Frequently used techniques for soft ground improvement are discussed. The factors that contribute to the stability of the road embankment are reviewed by approach, results of past studies, and historical cases. The findings show that settlement, slope stability, and soil bearing capacity are all challenges to constructing the road embankment. Additionally, it is found that geometric data is a key factor in embankment design. Pre-loading with prefabricated vertical drain (PVDs) methods and lightweight fill were found to be widely used techniques in soft ground improvement. The information from this study can be used to develop design guidance systems, numerical modelling, and to give an overview and knowledge to other researchers who are or will conduct research in this field. Finally, future perspectives for research are related to predictions of factors that affect the stability of road embankment with an artificial intelligence approach. ABSTRAK: Kertas ini membentangkan ulasan kajian menyeluruh mengenai cabaran yang dihadapi dalam pembinaan benteng jalanraya di atas tanah lembut dan mencadangkan ke arah pembangunan kajian masa depan. Teknik-teknik penambahbaikan tanah lembut yang sering digunakan turut dibincangkan. Faktor- faktor yang menyumbang kepada kestabilan benteng jalanraya diulas dengan pendekatan kepada kajian lepas dan sejarah kes. Hasil kajian ini didapati bahawa enapan, kestabilan cerun dan keupayaan galas tanah merupakan cabaran dalam pembinaan benteng jalanraya. Selain itu, ia didapati bahawa data geometri merupakan faktor penting kepada rekabentuk benteng. Kaedah pra pembebanan dengan prefabrikasi saliran menegak (PVDs) dan isian ringan didapati teknik yang popular digunakan dalam pembaikkan tanah lembut masa kini. Maklumat dari kajian ini boleh digunakan untuk membangunkan sistem panduan reka bentuk, pemodelan berangka serta memberi gambaran dan ilmu kepada penyelidik lain yang sedang atau akan menjalankan kajian dalam bidang ini. Akhir sekali, perspektif masa depan untuk penyelidikan berkaitan ramalan faktor-faktor yang mempengaruhi kestabilan embankment jalanraya dengan pendekatan kepintaran buatan.

“…This load transfer is also referred to as the soil arching effect (Iglesia et al, 2014;Girout et al, 2016;Huckert et al, 2016;Rui et al, 2016;Smith and Tatari, 2016;Villard et al, 2016;Ghazavi et al, 2018;Girout et al, 2018;King et al, 2018;Pham et al, 2018). Usually, a load transfer platform is constructed above the top of the columns to eliminate this differential settlement, and one or several layers of geosynthetic reinforcements (Shukla and Chandra, 1994;Hinchberger and Rowe, 2003;Rowe and Li, 2005;Ariyarathne et al, 2013;Abu-Farsakh et al, 2016;Zhao et al, 2016;Da Silva et al, 2017;Feng et al, 2017a;Ghosh et al, 2017aGhosh et al, , 2017b are sandwiched therein to strengthen the load transfer platform. Some researchers have applied fiber or tire mixtures to improve the strength of this platform (Bordoloi et al, 2015;Zhang et al, 2015aZhang et al, , 2015bDisfani et al, 2017;Bordoloi et al, 2018;Indraratna et al, 2018).…”

“…In recent years, there has been an increasing interest among researchers in settlement predicting [10], simulating the behaviour [11] and developing analytical solutions [12] of the embankment with PVDs. Factors found to be influencing embankment stability with PVDs have been explored in several studies [13]- [15]. However, a major problem with this kind of application is that its effect on stability is limited in the existing literature.…”

This article provides an assessment study of the embankment stability on soft soil improved with prefabricated vertical drains (PVDs). An empirical approach based on Barron theory is used to predict settlement grounds with PVDs and compared to measured. This comparative study is essential to validate the soil parameters in analyzing the stability of the embankment with a limit equilibrium method (LEM). The effectiveness of PVDs and geotextiles installations has also been investigated in stabilizing the soft soil beneath the embankment. This study reveals that the ground improvement by PVDs has an effect on reducing the vertical displacements of subsoil. The geotextiles installed under the embankment provides higher stability to the surface soil, and the maximum settlement can be reduced in the long term period.
