A Study of the Behavior of Precast-Concrete-Component Embankment on the Soft Ground
Embankments made of precast concrete components are now widely applied in Ho Chi Minh City and surrounding areas to protect the riverbank with the advantage of shortening the construction time and stages, reducing the construction load. Hollow reinforced concrete block embankment is one of the precast-concrete-component embankments constructed in Ho Chi Minh City. More specifically, in Palm Marina area, Long Truong Ward, Thu Duc City, Ho Chi Minh City, the construction of this type of embankment on the pre-stressed reinforced concrete pile foundation started in 2020. However, some embankment sections were eroded in January 2022 during the leveling phase, the main bearing piles are displaced, causing the assembled reinforced concrete block to subside and deviate from the embankment route. The study focuses on the PLAXIS 3D model of this embankment structure on the soft ground of the area to analyze the behavior of the embankment. It is realized that the project area is located in soft ground with a maximum thickness of silt layer of 18 m. However, the existing pile option does not guarantee the bearing capacity of the embankment, leading to instability of its system. Increasing cross-section and number of rows of piles is proposed in this study to enhance the stiffness and ensure the stability of the embankment.
