Optimization Study on Grouting Method Based on the Grouting Intensity Number

Guest Editor Yuantao Teng (Jilin Normal University, Shiping City, China)

Conventional grouting methods that are widely used in the foundation treatment is analyzed and compared with the grouting intensity number method. It is obtained that conventional grouting has a disadvantage of rock lift-movement and seepage flow, which brings about serious surface crack and body damage for the dam foundation. The grouting intensity number method can achieve fracture plugging effectively so as to decrease the rate of permeable rock mass, which makes it have strong resistance for erosion and piping damage. By comparison with the two grouting methods, analysis results showed that the grouting intensity number method overcame the shortages of conventional grouting and had an advantage of high stability and safety. This study has a great significance for the development of effective foundation treatment method in hydraulic construction projects.
