Application situation of optical fiber strain sensor used in bridge structure state monitoring is detailed introduced in this paper, two bridges which optical fiber strain sensor is adopted in construction stage stress monitoring and long-time stress monitoring in our country are introduced as example. According to the theoretical analysis of structures, the strain monitoring locations are selected. The composite technology between optical fiber strain sensor and concrete is researched. The installation technology and protect method between optical fiber strain sensor and steel girder are extracted, and advanced acquisition software is explored. Finally, the application foreground of optical fiber strain sensor is discussed. The research result indicates that the optical fiber strain sensor is extraordinary suitable for state monitoring of bridge structure because it has the merits of light structure and reliable performance.

Monitoring Technologies

The measuring methods using optical fiber strain sensors are being considered as structural monitoring technologies for concrete structures. B-OTDR method using optical fiber strain sensors can measure continuous strain along an optical fiber over 80km. Because of this advantage, it is expected to measure deformations in large-scale structures. But, this new measuring method, B-OTDR method, is just in development. There is very few case of applying this measuring method to actual structures. This paper describes a new measuring method using optical fiber strain sensors (B-OTDR method) applying to an actual concrete underground tunnel which was expected to deform by new shaft work near this tunnel. As a result, this method using optical fiber strain sensors can measure the deformation of the underground tunnel.

A low-cost wastewater disposal system was commissioned in 1959 to treat domestic and industrial wastewaters generated in the Latrobe River valley in the province of Gippsland, within the State of Victoria, Australia (Figure 1). The Latrobe Valley is the centre for large-scale generation of electricity and for the production of pulp and paper. In addition other industries have utilized the brown coal resource of the region e.g. gasification process and char production. Consequently, industrial wastewaters have been dominant in the disposal system for the past twenty-five years. The mixed industrial-domestic wastewaters were to be transported some eighty kilometres to be treated and disposed of by irrigation to land. Several important lessons have been learnt during twenty-five years of operating this system. Firstly the composition of the mixed waste stream has varied significantly with the passage of time and the development of the industrial base in the Valley, so that what was appropriate treatment in 1959 is not necessarily acceptable in 1985. Secondly the magnitude of adverse environmental impacts engendered by this low-cost disposal procedure was not imagined when the proposal was implemented. As a consequence, clean-up procedures which could remedy the adverse effects of twenty-five years of impact are likely to be costly. The question then may be asked - when the total costs including rehabilitation are considered, is there really a low-cost solution for environmentally safe disposal of complex wastewater streams?
