Abstract:
This project is ground improvement work for seismic reinforcement with the increase of the design water depth of the Sakata port. Soil layers of the quay is composed of landfills which is surface, on the mixed soil, sand gravel and clay existing partially. As a result of comparative study, V-JET method and multi-fan method were adopted for reinforcement measures. In this paper, we report the quality and finished-shape management of ground improvement work by V-JET method and multi-fan method, and measures of displacement reduction for facilities and quays in service. Key words?Coal-fired power plant, Seismic reinforcement, V-JET method, Multi-fan method
