摘要
文章结合云南山区自然地理以及涵洞现状,总结了公路涵洞"上淤"、"下冲"水毁的成因,提出了进水段束流、洞身段速流、出水段缓流等具体有效的防治措施,以期为山区公路涵洞修建提供参考。
According to the nature, geography and status of culverts of Yunnan province, the causes for highway culvert washout are summarized, and effective protective measures of restricting flow at entrance zone, speeding up flow at the culvert trunk and slowing down flow at the outlet zone are put forward, which could be taken as reference for highway culvert construction in mountain area.
