摘要
使用微型组合抗滑桩结合其它工程措施治理滑坡是目前滑坡治理领域的一个新趋势,因其施工便利、压力注浆提高滑坡自身稳定性显著以及治理费用较低等优点,目前已大量应用于工程实践。以青海省西久公路某滑坡为例,在分析滑坡存在浅层和深层2个滑动带的基础上,提出采用微型组合抗滑桩结合锚拉式框架梁加固并使用仰斜排水孔的综合治理措施,通过治理后的稳定性验算和雨季暴雨的考验,证明了微型组合抗滑桩的综合措施的可行性和有效性。
It is a new trend to control landslide by using anti-sliding composite structure of micro-piles combined with other engineering measures, which has been largely applied in engineering practice for its convenient, low cost and high landslide stability being obviously increased by pressure grouting.Taking a landslide case of Xining-Jiuzhi highway as an example and based on the analysis on 2 existing slip zones of shallow layer and deep layer, a comprehensive landslide treatment measure is put forward：micro combined anti-sliding pile is applied with anchor frame beam consolidation and inclined drain holes.By the stability computation and rainfall test in rainy season, the feasibility and effectiveness of the comprehensive treatment measure by micro combined anti-sliding pile are proved.
