摘要
在龙蒲高速建设过程中路基挖方边坡、小桥涵洞进口沟谷均出现大面积涎流冰病害。文中对造成桥涵阻塞及路桥水毁的原因经过调查和分析,分别结合项目涎流冰的类型、特点、规模,在保证工程质量和安全下,采取排、挡、积、截等工程处治措施,后期实施效果较好。为日后季冻区治理涎流冰病害的设计工作提供参考。
During the construction of Longpu Expressway,a large area of salivary ice hazard occurred in the excavation slope of subgrade and the inlet of the bridge culvert.In this paper,combined with the characteristics and scale of salivary ice of the project,engineering treatment measures such as drainage,retaining,accumulation,and interception were taken to ensure the project quality and safety after the investigation and analysis of culvert blockage and bridge damage.With the good effectiveness,the proposed mathods may provide a reference for the design of controlling salivary ice disease in seasonal freezing area in the future.
