摘要
受季节冻土区的影响,灌区渠道边坡尤其是大型挖方渠道高边坡普遍存在大面积冻融坍塌破坏问题,且这种破坏基本由渠道边坡土壤排水不畅所致。本文通过对季节冻土区渠道冻融滑坡破坏的机理分析,研究提出了渠道高边坡深层排水锚固抗冻融防护型式。该防护型式起到了排水与锚固的双重作用,具有工程造价低、施工简单等特点,为季节冻土区高边坡渠道防护提出了新的思路和方法。
Based on the analysis of the failure mechanism of frozen-melt landslides in seasonal frozen soil areas,this paper proposes a deep-drainage anchorage anti-freeze-thaw protection pattern for high slopes.The protection type has the dual functions of drainage and anchoring,and has the characteristics of low engineering cost and simple construction, and proposes new ideas and new methods for the protection of high slope channels in seasonal frozen soil areas.
