摘　　要：本课题组一直持续对混凝土芯样的研究工作,获取了大量的研究数据,通过数据分析总结,得出芯样直径、高径比、取芯方向及端面平整度对抗压强度的影响结论,提出加大微小芯样或者短芯样的研究,更好地为工程质量建设服务。The research group has been continuously working on the concrete core samples,and has obtained a large number of research data.Through data analysis and summary,it has come to the conclusion that the core sample diameter,height diameter ratio,coring direction and end face flatness have an impact on the compressive strength,and it has put forward to increase the research on micro core samples or short core samples,so as to better serve the construction of project quality.

关 键 词：芯样 强度 高径比 直径 平整度
