摘要
为深入研究豆石型灌浆料的力学性能和变形性能,在前期试验研究的基础上,对豆石型灌浆料的尺寸效应、强度转化、不同龄期强度以及应力应变曲线进行了试验研究。研究得到了尺寸效应系数和强度转化关系,给出了不同龄期强度的预测公式,绘出了豆石型灌浆料轴压应力应变曲线,对比了其与混凝土曲线的不同。
In order to research the mechanical properties and deformability of pisolite grouting material （PGM）, based on the earlier study, size effect, strength translation, different age strength and stress-strain curve of PGM were studied. By analyzing the experimental results, size effect coefficient and strength translation relation were obtained, the strength calculation formulas on different age of PGM were proposed, the stress-strain curves of PGM was plotted and the stress-strain curve of PGM and the one of ordinary were compared.
