The utility model proposes ship lock structural strain and stress distribution formula optical fiber monitoring device, comprise distributed sensing optical cable, data acquisition equipment, data processing and analysis module; Distributed sensing optical cable being laid in shiplock head floor, water delivery gallery, the lock floor of ship lock with the mode of main muscle colligation, top, the end or the inside and outside surface on lift wall reinforced concrete top layer forms U font loop; After distributed sensing optical cable completes with the shiplock head floor, water delivery gallery, lock floor, the top layer concreting of lift wall reinforced concrete that are laid in ship lock with the mode of main reinforcement colligation, sensing optic cable is apart from concrete surface 5-10cm; Sensing optic cable will produce deform in same pace with reinforced concrete structure, and Fibre Optical Sensor produces corresponding strain; Set up data acquisition website at lock head top, laid sensing optic cable link tester is crossed to optical cable connection data and gather website. |
