摘　　要：以配制豆石型灌浆料时的加水量和所掺豆石量为研究参数,研究上述参数对豆石型灌浆料工作性能和力学指标的影响。研究表明,对于所研究的豆石型灌浆料,其在13%加水量下具有较好的工作性能;其力学指标随加水量的增大而降低;当加水量小于14%,豆石含量小于35%时,力学指标随豆石掺量的增大而提高。此外,研究还发现,豆石型灌浆料的抗拉强度要比同等级的普通混凝土高40%左右。最后,通过分析试验数据,给出了各力学指标之间的回归公式。The effects of different amount of water and pisolite on the workability and mechanical properties of pisolite grouting material（PGM） were studied. The results showed that the workability of PGM with 13 % water content was better, the mechanics indexeal of PGM decreased with the increment of water, and increased with the enhancement of pisolite when the amount of water less than 14% and pisolite less than 35%, moreover, tensile strength of PGM was approximately 40% higher than that of ordinary concrete. Finally, based on the experimental data, the regression formulas among mechanical indexes were put forward.
