A slope in Shaoguan of Guangdong Province is composed of soils with high water adsorption. Rainstorms usually decrease strength parameters of soils and lead to great landslide with severe soil disturbance. A popular unloading and anti-sliding supporting method usually cannot achieve a good treatment effect. The closely spaced steel-tube and compressive grouting method

with two or more line steel flower tubes drilling into anti-sliding section of sliding mass and compressive grouting

can reinforce the soil around steel tubes. The steel tubes and around soil can form a solid continuous integrality acts as a retaining wall. Steel-tube and compressive grouting improve the mechanical capability of soil obviously so that the stability of slope is recovered with special unloading along slope and drain measures together.
