摘要
泥石流是天山公路最主要的地质灾害,也是迄今尚未解决的公路病害。基于天山公路泥石流爆发诱因、物源组成、岩性特征、运动规律,遵循高寒地区公路泥石流防治的特殊性,所开发的导流墙网、排导棚架结构、桩板泄流槽、导流弧形挡土墙技术,是该类公路泥石流极其有效的防治技术。根据这些单体技术结合已有公路泥石流的防治技术,构建了包括导流墙网+排导棚架、桩板泄流槽+底埋隧道及导流弧形挡土墙等结构在内的泥石流综合防治体系,有效地解决了天山公路泥石流病害的防治问题,研究结果已用于天山公路泥石流防治方案设计,也为同类型公路泥石流治理提供了重要的技术借鉴。
Debris flow is not only uppermost geological disaster in Tianshan highway, but also unfathomed up to now. On the basis of occasion of debris flow, substance composes of fountainhead, lithology character, athletics rule, and followed prevention particularity of debris flow in high-cold area, exploder lead flow wall-net, evacuate shelf structure, peg-board evacuate launder and camber lead-flow block wall are the most effective prevention technics on highway debris flow. Hereby, integrated prevention technics are established such as lead flow wall-net combined with evacuation shelf, peg-board evacuation launder combined with tunnel burying underground, and camber lead-flow block wall, which effectively solve prevention problems on Tianshan highway disaster. The results are used to prevention project design of Tianshan highway debris flow,and provide the important technical reference on same type highway debris flow.
