Pile foundation is often used in the construction of communication tower in the karst region. Stability of pile foundation to support roof is related safety of the superstructure equipment. No deep special study on stability of pile foundation in karst region has been reported yet. Reliability of evaluation results by traditional qualitative analysis method and semi-quantitative analysis method needs further discussions. Studying stress and deformation characteristics of pile foundation system to support roof deeply has important theoretical and practical significance to improve understanding of the problem. In this study, effects of pile foundation for the communication tower in a karst region on cavity roof of underlying karst were discussed by FLAC3d numerical simulation. Stress and deformation characteristics of roof under loading of pile foundation were analyzed. The relationships between depth of pile bottom and settlement of pile foundation and displacement of roof were discussed. Research conclusions can offer certain references to design, construction and operation monitoring of the project, as well as some references for similar engineering constructions.
