全级配混凝土试验对高拱坝抗震安全设计具有重要的意义,但由于对设备要求很高,国内成功试验经验很少。基于中国水利水电科学研究院15 MN大型动态材料试验机研究了全级配混凝土拉、压、弯试验方案,并给出了切实可行的试验方法,为充分发挥大型材料试验机的领先优势积累了宝贵经验,亦为推动全级配混凝土力学特性深入研究奠定了基础。
Full grade concrete test is of great significance to the seismic design of high arch dam. However, due to the high requirement of equipment, there are few successful experiments in China. Based on the 15 MN large-scale dynamic material testing machine of China Institute of Water Resources and Hydropower Research, the experimental program of tension, compression and bending of fully-compounded concrete was studied and the practical test methods were given. In order to give full play to the leading advantages of large-scale material testing machine Valuable experience, but also to promote full grading mechanical properties of concrete laid the foundation for further study.
