摘要: A fiber Bragg grating (FBG) sensor network has been installed into a large diameter concrete pile on real construction site. The intention was to monitor its deformation behavior during several quasi-static loading cycles. skin friction between and subsoil affecting the ultimate bearing capacity of as well settlement structure under investigation derived from our measurements. comparison results sensors conventional strain gages (CSG) shown excellent correspondence.
