EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES AND DEFORMABILITY OF PISOLITE GROUTING MATERIAL
-
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。Abstract: 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.
