水泥-水玻璃双液注浆力学特性的试验研究
Experimental study on mechanical characteristics of cement-silicate double solution grouting
摘要
Abstract
The experiment was carricd out by measuring high-precision inclinometer pipe deformation of 0.5 me-ter away from grouting center with grouting pressure 0.4 MPa and grouting age 1,2,4 and 12 h, and combining finite element software ABAQUS. The cement-silicate double solution grouting mechanical properties of different grouting age and different grouting depth was then studied. The results show:at grouting age of 1,2,4 and 12 h, the grouting force generated by cement-silicate double solution grouting increases at first, and then decreases and thereafter continually increase, with the minimum value appears at grouting age of 2 h;At different grouting age, the maximum inclinometer deformation stress Mises appears in central depth of grouting soil, and the second lar-gest deformation stress of inclinometer appears in the critical position between grouting soil and no grouting soil.关键词
