This paper represents the design program, dynamical calculation model and calculation results of the coalbreaker's vibrating\|insulation foundation in the phase 2 project of Wenzhou power plant.A model test, which is based on the primary design program, with a geometrical scale of 1∶8, is made. The results obtained from the above test verify that the calculation model and the calculation results are correct and show that the displacement of the coalbreaker's vibrating\|insulation foundation caused by the vibration is within the range of the criterion. Furthermore, the test results also show that the vibrating\|insulation foundation has high positive vibrating \|insulation efficiency, then the sub\|structure could be designed by the static analysis. \;
