摘　　要：通过改变配合比中脱硫石膏粉的掺量,研究脱硫石膏对预拌盾构同步注浆料的流度、固结率、28 d抗压强度、凝结时间等性能的影响及其规律,通过改变配合比中脱硫石膏粉的掺量,并比较试验结果得出最优比例的脱硫石膏。By changing the content of desulphurized gypsum powder in the mix,the influence of desulphurized gypsum powder on the fluidity,consolidation rate,28d compressive strength,setting time and other properties of the pre-mixed shield slurry subject to simultaneous grouting was studied.The optimal ratio of desulphurized gypsum was obtained by changing the content of desulphurized gypsum powder in the mix and comparing test results.
