Maintenance management plan for sabo facilities considering life cycle costs

Norio HARADA, Yoshifumi SATOFUKA and Takahisa MIZUYAMA


In 2019, the maintenance and management procedures in place for Sabo facilities, including the maintenance and postmaintenance phases, were reviewed. We proposed a quantitative method for evaluating the soundness of Sabo facilities based on maintenance methods used for other structures. However, a maintenance method that takes into account the costs incurred over the life cycle of Sabo facilities is urgently needed. We then analyzed the degree of deterioration of Sabo facilities according to previous inspection reports. We present a method for developing Sabo maintenance management plans with consideration of life cycle costs.
