摘要
某公路隧道洞口位于傍山冲沟瀑布下方,雨季面临冲刷威胁,影响通行安全。为此,文章综合考虑结构安全、运营安全、景观保护与成本控制,提出了针对性防冲刷设计方案,通过适度延长明洞、在洞顶设置受水池并整合截排水系统,实现对洞口的有效防护。同时,详细阐述了设计思路、过程、关键问题与控制要点。实践表明:该设计不仅有效抵御了冲刷作用,保障了洞口结构稳定与行车安全,同时最大程度地保留了冲沟瀑布的自然景观,使隧道与周边环境和谐相融。研究成果为类似工程提供了有益借鉴,也为隧道洞口设计在安全、环保与美观方面的统筹提供了新思路。
The entrance of a highway tunnel is located beneath a waterfall in a mountain gully,facing erosion threats during the rainy season that affect traffic safety.To address this,the study proposes a targeted anti-erosion design scheme taking into account structuralsafety,operational safety,landscape preservation,and cost control.The scheme effectively protects the tunnel entrance by moderately extending the open-cut section,installing a water-receiving pool on the top,and integrating a water interception and drainage system.The paper elaborates in detail on the design concept,process,key issues,and control points.Practice shows that this design not only effectively resists erosion,ensuring the structural stability of the entrance and driving safety,but also preserves the natural landscape of the gully waterfall to the greatest extent,achieving harmony between the tunnel and its surrounding environment.The researeh results provide valuable references for similar projects and offer new ideas for integrating safety,environmental protection,and aesthetics in tunnel entrance design.
