| 摘 要： | 京珠高速公路某高边坡处于山前堆积层中,地层主要由亚粘土、块石及石英砂岩组成,堆积层中地下水发育.预应力锚索施工时,恰适雨季来临,几场突如其来的大雨使边坡由局部变为整体蠕动.由于时间所限,靠预应力锚索等加固措施已不足以防治,为此提出微型桩加固方案.在此次抗滑抢险施工过程中,微型柱作为临时加固措施起重要作用.本文主要介绍了锚索施工过程中滑坡的产生,同时也阐述了微型桩的作用机理及其施工工艺.

| Abstract: | The high slope along Jing-Zhu high road is situated in the accumulated beds before hills.The strata of it are made of sandy clay,block and quartzite and the groundwater is developed.It was rainy season when constructed pressure anchor,the slope slided from part to whole because of heavy rain.Owing to the limitation of time,pressure anchor and other reinforce methods were not enough to prevent the sliding.The reinforce plan of minipiles had been put forward.As temporary reinforce mtehods,minipiles take great effect.The author in this paper introduced landslide occurrence in the course of anchor construction,mechanism and construction technology of minipiles. |
