Research on Computing Method of Similarity Scale of Dynamic Model Test Concerning Fluid-Structure Coupling for Water-Conveyance Tunnel

Abstract:

Based on the research of numerical simulation of model experiment of water-conveyance tunnel in under soft soil, and three basic types of similarity relation ship between the prototype and the model for dynamic structural model test and dynamic rupture model test was proposed, and the situation where various similarity relation ship is applicable and the technique to ensure similarity for the different goal (to study dynamic behavior, elastic response or damage pattern) was discussed, the similarity relation and the technique is proposed according to specific selection of material of model test . At one time the similarity relation and the technique is validated to pass a example. The results of numerical simulation show: in the specific thing, the similarity relation completely from data of the model test transfer to the prototype. Some new ideas to keep the similarity of the embankment structures are introduced.
