摘要：
Steel strut plays an important role in controlling deformation and maintaining the pit stability in strutted retaining structure. Axial force in the steel strut is influenced by temperature obviously because of the steel thermal characteristic. By simulation in FLAC3D of an actual project, the axial force in steel struts is analyzed when temperature rises. The origin axial forces that may influence the force changes are discussed. The way that axial force changes approximate linearly with temperature rises in the numerical model is basically consistent with the monitoring. This conclusion could provide a useful reference for engineering and construction in similar deep excavation projects.
