【摘要】 钢管压力注浆型抗滑挡墙是一种将注浆方法与微型桩群方法联合使用的技术,受力分析时可看做一个抗滑挡墙,其最大特点是将滑坡中的一部分滑动体加固成抗滑体来达到对滑坡治理的目的。采用钢管压力注浆型抗滑挡墙对京珠高速公路K108滑坡进行加固,并结合截排水隧洞排出滑体内地下水;通过滑坡测斜孔的位移监测分析,得出滑坡已处于稳定状态, 达到了滑坡治理的目的。更多还原

【Abstract】 Steel-tube bored grouting anti-sliding retaining wall is a technique combined with grouting and micropiles, treated as the retaining wall in mechanics analyzing. It is the significant feature that steel-tube bored grouting anti-sliding retaining wall Change the partial sliding mass to anti-sliding mass. Taking the case of landslide located in south K108 of Guangdong segment of Beijing-Zhuhai highway, the landslide is reinforced by steel-tube bored grouting anti-sliding retaining wall and discharged groundwater from sliding mass. The K108 landslide is in the situation of stability by means of displacement analysis on monitoring bores and stability computation. The result of treatment show that the steel-tube bored grouting anti-sliding retaining wall is an effective method on treating landslide.更多还原
