川藏高速公路喇叭嘴泥石流、滑坡、崩塌、弃渣、高填综合处治

通过对川藏高速公路雅康段喇叭嘴泥石流、滑坡、崩塌、弃渣、高填路堤的复杂地质灾害体的工程地质分析、灾害机理研究和综合处治方案优化得出:多类型复杂地质灾害体的处治，应充分掌握地质资料，在对各地质灾害体进行针对性处治的基础上，贯彻兼顾关联地质灾害体的综合处治理念；复杂地质环境下的高速公路通过形式应有利于提高地质灾害的安全防护等级，并综合考虑工程建设管理风险，适当提高安全冗余；喇叭嘴段泥石流的有效处治为合理采用“桥改路”反压滑坡，结合柔性明洞提高线路的崩塌落石抗灾能力，以及弃渣、高填的分隔治理奠定了基础；复杂地质环境下的工程建设应加强工程地质深度，有效控制工程风险和加强环境保护。

Comprehensive Treatment of Debris Flow,Landslide, Collapse,Waste Slag and High Embankment in the Labazui of Sichuan Tibet Expressway

Based on the engineering geological analysis, disaster mechanism study and comprehensive treatment scheme optimization of the complex geological hazards of debris flow, landslide, collapse, waste residue and high embankment in Yakang section of Sichuan-Tibet expressway, the following conclusions are obtained: for the treatment of multi-type complex geological hazard body, geological data should be fully collected and analyzed;on the basis of targeted treatment of geological hazards, comprehensive treatment of related geological hazards should be carried out;highway passage form in complex geological environment should be conducive to improving the safety protection level of geological hazards, and comprehensive consideration of engineering construction and management risks, appropriate improvement of safety redundancy;the effective treatment of debris flow in the Labazui section lays a foundation for the rational use of "bridge-to-road" back-pressure landslide, combined with flexible open-pit to improve the ability of line collapse and rock disaster resistance, as well as the separation treatment of waste residue and high fill;engineering construction under complex geological environment should strengthen the depth of Engineering geology, effectively control engineering risks and strengthen the environmental protection.
