Based on its characteristics, the modal synthesis method of substructures is applied to the dynamic analysis by considering suspended flexible layer as the link substructure, and the simplified equation of dynamic motion of a semi-flexible suspension structure is given.

Elastic plate is a main kind of ship shell components,the vibration induced by water flowalong the plate surface is considered as one of the causes of flow noise,and hence the problem about a plate covered by flexible layer is presented.

The polypropylene fibre concrete is the new kind of concrete flexible shotcrete layer forms in the soft rock tunnel supporting engineering.
