The study conducts numerical analysis of soil deformation during excavation retained by inclined retaining piles, particularly focusing on loose sand conditions.
The paper presents numerical analysis findings on soil deformation during excavation using inclined retaining piles, examining both internal and external soil displacement behaviors.
The study is authored by Y. Wang, X. Cheng, and G. Zheng, with affiliations unspecified.
Published recently, with the findings reflecting contemporary urban construction practices and challenges related to excavation stability.
The research findings apply broadly but stem from model tests indicating behaviors of soil and retaining structures which can be relevant for urban environments and construction sites using inclined piles.
This research aims to address the issue of soil displacement during foundation pit excavation, which can compromise the stability of surrounding structures and facilitate effective engineering solutions.
The study employs finite element modeling to simulate soil and structural interactions, validating findings through model tests.
There is increasing attention to the innovative use of inclined retaining structures, as these have not been widely studied compared to traditional methods.
"When the inclination angle of the piles is small (such as 10°), all or most of the soil between the piles is compressed in the horizontal direction." - attributed to the authors of the article.
"When the inclination angle of the piles is large (such as 20°), all or most of the soil between piles is in a relaxed state in the horizontal direction, and the piles deform independently." - attributed to the authors of the article.
"The maximum displacement of the soil on the surface outside the excavation occurs around the retaining pile, and the displacement distribution patterns change with different types of retaining structures and inclination angle." - attributed to the authors of the article.
The article will commence by highlighting the significance of managing soil deformation during urban excavations, introducing the role of inclined retaining piles.
Explaining the necessity of effective excavation support, exploring existing methods, and the challenges posed by soil displacement.
Describing the finite element modeling process, the parameters involved, and the experimental validations carried out.
Presenting findings on soil behavior relative to pile inclination, emphasizing the compressed versus relaxed states of soil, and addressing practical engineering solutions.
Summarizing key insights, stressing the importance of this research for future excavation projects, and proposing areas for future studies.
