Frequent occurrence of landslides has seriously threatened the infrastructural projects in the Loess Plateau, China.
At the beginning, with development of the landslide, several fissures were generated along the internal weak surface.
Then, under the constant influence of rainfall and irrigation, the fissures were expanded and connected, which formed a consecutive sliding surface, consequently leading to the occurrence of the landslide.
Therefore, the key to treat the landslide is to prevent the expansion and connection of fissures in the potential slip zone inside the slope.
In this paper, an old landslide, which occurred at an early stage of the construction of the Lvliang Airport, was selected as a case study.
A new type of grouting material was used to fill the fissures and reinforce the loess in the slip zone, so as to study the effect of material content on the slope stability.
With current methods, loess specimens were taken from the slip zone inside the Lvliang Airport slope.
Based on the GDS triaxial test system, a series of laboratory tests were performed on the undisturbed loess and the remolded which contained the stabilizer, including triaxial shear tests at constant matric suctions and wetting tests at constant deviator stresses.
Moreover, the dichotomy in mathematics was chosen to find the threshold of the material content.
The test results showed that the cohesion and the internal friction angle of the loess obviously increased after grouting.
The failure behaviour of the loess along the wetting path was dependent on the material ratio and the stress level.
Meanwhile, the critical state line of the slope, grouted with materials of different ratios, was compared by fitting the regression equation.
It was found that the threshold value of the stabilizer content was between 15% and 20%, which was the most suitable ratio for improving slope stability with relatively lower cost.
