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 the main geological disaster on the Tianshan Highway, and it is also a hitherto unresolved road disease. Based on the causes, source composition, lithology characteristics and movement of debris flow in Tianshan Highway, and following the particularity of debris flow prevention and control in the highway in the alpine region, the diversion wall network, draining scaffolding structure, Arc retaining wall technology is an extremely effective prevention and control technology for this type of highway debris flow. According to these monolithic technologies combined with the prevention and control technology of existing road debris flows, debris flows including structures such as diversion wall network + drainage scaffolding, pile plate drainage tunnel + buried tunnel and diversion arch retaining wall are constructed The comprehensive prevention and control system has effectively solved the prevention and cure of the debris flow disease on the Tianshan Highway. The research results have been used in the design of the debris flow prevention and control program for Tianshan Highway, and also provided important technical reference for the debris flow control on the same type of highway.
