Abstract

<p>　Regarding the seismic retrofitting of sewerage facilities, seismic retrofitting methods have been developed for each of the countermeasures against manhole floatation due to liquefaction and the joints between manholes and sewage pipes, which are structurally susceptible to damage, has been applied. However, each seismic retrofitting method has been applied independently, and the combined effects have not been studied. In addition, sewerage facilities are built as an integrated system with manholes and sewer pipes forming a network, so it is necessary to evaluate the seismic resistance of manholes and sewer pipes in an integrated structure. Therefore, in this study, using a centrifugal model test equipment, we report the evaluation of seismic resistance by combining various seismic retrofitting techniques.</p>
