中文摘要：
在动态装载下面学习集体水泥的弯曲强度，三等级的具体横梁的纯弯曲地区是被考虑一三阶段合成在他们之间的矩阵，总数和接口在上镇静中央级。动态组成的模型考虑紧张率加强效果和损坏弄软效果被采用描述 cocrete 和 meso-element 的损坏。在装载的影响下面的横梁的失败机制， triagle 波浪负担，动态负担结合起始的静态的装载被使用模仿控制排水量女性。而且，标本的压力紧张曲线和他们的动态弯曲强度被获得。从数字模拟获得的结果与试验性的数据同意了很好。
英文摘要：
To study the bending strength of mass concrete under dynamic loading, the pure bending zone of three-graded concrete beam is considered as a three-phase composite composed of matrix, aggregate and interface between them on meso-level. Dynamic constitutive model considering strain-rate strengthening effect and damage softening effect is adopted to describe the cocrete and meso-element＇s damage. The failure mechanisms of beam under impact loading, triagle wave load, dynamic load coupling with initial static loading were simulated by using displacement-controlled FEM. Furthermore, stress-strain curve of the specimens and their dynamic bending strength were obtained. The results obtained from numerical simulation agreed well with experimental data.
