一、前言动力模型材料是进行坝体振动模型试验的重要环节,近年来国内外许多科研部门对动力模型材料曾进行过不少研究工作,提供了一些合成材料,这些材料大体上可归结为弹性材料和脆性材料两大类。目前,国内在结构动力模型试验中,采用的模型材料有加重硫化橡胶材料,胶乳水泥材料、软胶及冻粉材料等。加重的环氧橡皮泥合成材料是我们结合混凝土坝振 I. INTRODUCTION Dynamic model material is an important part of dam body vibration model test. In recent years, many research departments at home and abroad have carried out many researches on dynamic model materials and provided some synthetic materials. These materials can be generally attributed to the elasticity Materials and brittle materials are two major categories. At present, the model materials used in the structural dynamic model test are vulcanized rubber materials, latex cement materials, soft rubber and frozen powder materials. The heavier epoxy plasticine synthetic material is combined with concrete dampening
