公路小桥涵水毁灾害调研与防治措施

Survey and Prevention of Water Damages of Highway Bridges and Culverts

为了提高山区公路沿线小桥涵抵抗水毁的能力,改善山区高等级公路的交通状况,通过对山区高等级公路沿线小桥涵洞水毁类型及成因的调查和分析,结合个人工程经验,提出了相应的预防对策。水毁的主要类型有水压力破坏、拥堵破坏、冲刷破坏、渗漏破坏、地质破坏;预防对策主要提出了进出口铺砌防冲刷、消能防冲刷,以及提升洞深强度、预防涵洞阻塞等方面的措施。

In order to improve the ability of the mountain highway culverts to resist water damage, to improve the traffic conditions of the mountain of high - grade highways, with the investigation and analysis of the types and causes of the mountainous area along the high - grade highway culverts＇ destruction, combined with personal experience in engineering, proposed the corresponding countermeasures. The main types of water damage have water pressure damage, congestion destruction, erosion damage, leakage destruction, geological destruction ;Countermeasures mainly proposed the import and export＇ s paved anti - erosion, energy dissipation and erosion, as well as enhancing the hole＇ s deep strength, the measures of prevention for culverts obstruction.
