【摘要】 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。更多还原

【Abstract】 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.更多还原
