Huge coal silos whose capacity is 70000-ton are constructed at Tachibana-wan power plant. While filling and discharging, coal pressures and structural stresses are measured to verify the design loads. The results show that there is good agreement with the design and the measurement and that the structural deformations seem to be elastic. However, as far as the pressure distribution in the hopper area concerned, the tendency that higher. parts show higher pressure is considered in the design, but the measurement shows higher values than predicted. This distribution is caused by the arch formation whose size of the largest arch is supposed to be half of the silo diameter.
