Abstract A series of physical simulation experiments were conducted to investigate effects of nanoparticles (carbon nanotube (CNT), graphene oxide (GO), nano-SiO2, and nano-Al2O3) on the grouting performance in dynamic water condition. Experimental results show that the use of nanoparticle could effectively improve the grouting performance. CNT composite grout was excellent for the maximal fluid pressure and residual grouts percentage. The sealing efficiency of nano-SiO2 composite grout was the greatest while that of nano-Al2O3 composite grout was the lowest among all nanoparticle composite grouts. The grouting performance increased with an increase of GO content.
