This paper investigates the use of BOTDA (Brillouin Optical Time-Domain Analysis) technology to monitor a large-scale bored pile wall in field. Distributed fiber optic sensors (DFOSs) were deployed measure internal temperature and strain changes during cement grouting, hardening, excavation-induced deformation secant wall. The study details geological conditions DFOS installation process. During increased by approximately 69 °C due hydration 30 min post-grouting, while decreased 0.5% on average slurry shrinkage. excavation, minimal, but excavation depth significantly influenced distribution, with continuous compressive observed two monitored boreholes. Two analytical methods, numerical integration method (NIM) finite difference (FDM), used calculate lateral displacement based data. results compared previous monitoring data, showing that was minimal after attributed high stiffness demonstrates effectiveness DFOSs for complex behaviors construction.

This study investigates the vertical bearing characteristics of single-pile foundations in complex karst areas, focusing on influence underlying cavities, eccentric and beaded cavities. Using both indoor model tests numerical simulations with ABAQUS/CAE 2020, load–settlement behavior, pile axial force, side friction distribution under these conditions are explored. The results reveal that presence cavities (eccentricity 2.5 d) significantly enhances ultimate capacity by 53% compared to concentric In contrast, reduce 12% due increased instability larger settlements. also examines effects backfilling characteristics, finding increases 111.8% prevents shear failure cavity roof. Backfilling improves stability reducing top settlement increasing 4.5%. novelty this research lies comprehensive consideration which often overlooked existing studies. These findings provide valuable insights for design regions, offering practical guidance how mitigate adverse optimize foundation stability.
