    Abstract
  • A cement-soil filling material is proposed for the quality problem of backfilling in narrow spaces that commonly exists in the development and utilization of underground spaces. The unconfined compressive strength test and direct shear test were conducted for the mixed fluid cement-soil. The effect of cement content, cement-soil ratio, curing method and curing time on the strength of cement-soil were studied, and the deformation modulus, cohesion and internal friction angle of cement-soil material were obtained. The experimental study shows that the mixed cement-soil has good physical and mechanical indexes. The deformation modulus is 98.4~112.7 MPa, the cohesion is 185.54~213.45 kPa, and the internal friction angle is 32°~39°, which can effectively reduce the surface settlement caused by the quality of backfill construction.
