黄土地区公路涵洞水毁特征及防治措施分析

Analysis on the characteristics and prevention measures of water damage of highway culverts in loess regions

因黄土的湿陷性,黄土地区涵洞水毁破坏较其他地区更为严重。为研究黄土地区公路涵洞水毁特征,通过对实际工程涵洞水毁类型及发生的原因进行统计分析,从工程设计、施工、养护角度对防止黄土地区涵洞水毁关键点进行了归纳。研究成果可为同类型涵洞的设计提供工程依据。

Due to the collapsibility of loess,the water damage to culverts in loess areas is more severe than in other areas.To study the characteristics of highway culvert water damage in loess areas,statistical analysis was conducted on the types and causes of actual engineering culvert water damage,and key points for preventing culvert water damage in loess areas were summarized from the perspectives of engineering design,construction,and maintenance.The research results can provide engineering basis for the design of similar culverts.
