| Abstract: | Grouting technique plays an irreplaceable role in engineering construction,with obvious economic and social benefits achieved. Great progress on grouting technology has been obtained at the same time. The new theory of grouting which considers the seepage effect of cement particle precipitation and the spatial temporal variation of slurry viscosity pro vides more accurate guidance for application of grouting technology in projects. Such new grouting materials as polymer grout ing material,CW epoxy resin,and microbial fluid provide more power for the development of grouting technology. New com puter techniques,including the micromechanical numerical simulation of PFC particle flow,provide a new way for the explo ration of grouting technology. The valuable achievements on grouting technology will promote the vigorous development of grouting technique. |
