摘要
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。
The study of complete grading concrete test is very important for seismic safety design of high arch dam, but the successful experiment is few for lacking high performance equipment. Based on the 15 MN large scale dynamic material testing system purchased by China Institute of Water Resources and Hydropower Research, test scheme is re- searched for direct tension, direct compress, bending test of complete grading concrete. It has accumulated valuable expe rience for giving full play of leading advantage of large-scale material testing system, and laid a foundation for pushing forward the research on mechanical properties of complete grading concrete.
