摘　　要：早期阶段的混凝土强度甚低,当受到外界力作用时,易发生损伤.本文对早期混凝土的静力损伤、爆破动力损伤及冲击损伤进行了试验研究和理论分析,提出了定量的分析方法和研究结果,可供工程应用参考.The strength of concrete in the early age is considerably low. It is easy to be damaged when external force acts on it. In this paper the experimental research and theoretical analysis for the damages to concrete in the early stage, which result from the action of static force, explosion wave in bedrock and impact, have been performed. Some analytical methods and results are presented for reference in engineering construction.
