| 摘 要： | 针对隧洞开挖施工中存在的爆破振动对混凝土衬砌的影响问题，就其试验研究的方法及爆破振动对混凝土强度的影响进行了探索和分析，得出了爆破振动速度与混凝土强度、在同一爆振速度下混凝土接受振动时的龄期与混凝土强度等关系曲线，从而确定出工程中所关心的安全振速、安全衬砌距离及合理衬砌时间等重要参数，并引用损伤理论对试验结果进行分析。

| Abstract: | Aimed at the effect of blasting vibration existed in tunnel excavation construction uponconcrete lining,this paper probes into and analyses the testing method and the effect of blastingvibration upon concrete strength.Thus,the relationship curves among blasting vibration velocityand concrete strength,and the period of concrete in recieving vibration and concrete strength inthe case of the same blasting velocities are obtained thereby determing the important parametersconcerning the safe vibration velocity, safe lining distance and rational lining time in engineering.Also, the damage theory is used to analyse the testing results. |
