内容記述 |
In recent years, a technique of asset management is being applied to maintenance and renewal of infrastructure facilities in consideration of a better fiscal management. Asset management of infrastructures focuses on the reduction and equalization of annual maintenance costs over the lifetime. In the field of river management, researches on the potential of maintenance cost reduction have been done for machinery and equipment, such as flood gates and sluiceway facilities. In such researches, however, social benefit and cost of the introduction of asset management, which are crucial in assuring the effectiveness, do not seem to be properly assessed. In this study, a social cost of losing the function of river management facilities is evaluated, taking sluiceway facilities for flood control as examples of such facilities. The social cost is assumed to consist of (i) maintenance and renewal cost of sluiceway facilities, and (ii) potential economic loss due to inundation resulting from the sluiceway facilities lost their functions. In the first step, the maintenance and renewal cost of sluiceway facilities for a particular year was calculated by aggregating cost items in maintenance schedule for the year, and future costs were also calculated by accumulating the annual costs. The result of this calculation revealed that the maintenance cost varies significantly from year to year. It also showed that the equalization of the costs over the lifetime is important, which implies the necessity of prioritization of facility maintenance. In the next step, to assess the importance of each facility and to prioritize the facilities, potential economic losses due to inundation supposing that these facilities lose their function were calculated by inundation simulations and flood damage impact studies. As a result of this study, a scheme of evaluating the facilities in terms of social cost reduction is presented. The scheme enables a quantitative assessment of the importance of each facility and helps to determine the priority of maintenance of the facilities. |
