摘要
随着山区公路建设的快速发展,高位崩塌灾害频发,严重威胁公路交通安全。基于川西高原雅西公路典型高位崩塌案例,通过地质调查、数值模拟分析,揭示了高位崩塌的成因机制,分析了崩塌能量,提出了分级被动防护+监测的防治方法。结果表明,不利的地形地质条件是基础因素,长期风化加剧了结构面劣化,降雨是诱发因素,雨水入渗导致危岩体蠕变进而发展为崩塌;采用被动网+明洞+智能监测系统的防治方法可有效对崩塌进行治理,防护方案可在峡谷地貌区推广使用。
With the rapid development of mountain highway construction,frequent high-positioned collapse disasters have posed serious threats to road traffic safety.Based on a typical high-positioned collapse case along a highway in the western Sichuan Plateau,geological surveys and numerical simulation analysis were employed to reveal the formation mechanisms of high-positioned collapses,analyze collapse energy,and propose a hierarchical passive protection combined with monitoring prevention method.The results indicate that unfavorable topographic and geological conditions serve as fundamental factors,with long-term weathering exacerbating structural plane deterioration.Rainfall acts as a triggering factor,where rainwater infiltration induces creep deformation of unstable rock masses leading to collapse development.The prevention method utilizing passive nets,open-cut tunnels,and intelligent monitoring systems proves effective for collapse control.This protection scheme can be promoted for application in canyon geomorphological regions.
