Abstract

Abstract

Strengthening and improving the sliding zone soil is helpful to improve the engineering properties of the sliding zone soil and the anti-sliding stability of the landslide. Taking the slope of a resettlement site project as the prototype， the physical model of the slope was constructed according to the similarity theory， and the physical model of the slope before and after grouting with ionic soil stabilizer was reinforced by artificial rainfall simulation device. The stress and displacement distribution of the tracing point of the slope were studied， and the failure mode and evolution process of the slope in rainfall conditions were analyzed. The test results showed that the soil pressure and pore water pressure were obviously influenced by ionic soil stabilizer on the reinforcement effect of slope sliding zone. After the sliding zone soil was grouted and strengthened， the critical rainfall amount and rainfall intensity leading to the deformation and failure of the slope model obviously increased， and the cumulative rainfall when the landslide occurred was about 9.14 times that before the reinforcement； the whole sliding collapse of the slope changed into local creep failure， and the duration of the slope sliding process increased， and the model shape basically remained intact after the creep failure. During the duration of destruction， the ionic soil stabilizer had good injectability， and the slope strengthened by grouting with ionic soil stabilizer was more stable. The improvement of sliding zone soil by ionic soil stabilizer could effectively improve the anti-sliding stability of the slope.
