广东省韶关某黏质土坡滑坡治理方法

韶关地区某土坡土质吸水性强，暴雨后土的强度参数明显降低，导致大面积滑坡，滑动土体受到严重扰动。采用一般的卸载抗滑支护方法无法达到理想的治理效果。在滑坡抗滑段采用两排或多排钢花管钻孔桩进行压力注浆，桩周围的土体被加固，形成一个坚固的连续整体，起抗滑挡墙作用。同时结合特殊的坡面卸载和排水措施，恢复了滑坡的稳定状态。

A repairing method for a clay landslide in Shaoguan of Guangdong Province

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.
