【摘要】 针对云南西部山区泥石流多发区设置在泥石流沟床中的桥墩容易遭受泥石流冲击直接危害桥梁的安全问题,文中结合桥梁、泥石流及水工等规范得出泥石流对桥墩冲击力的适用计算方法。以澜沧江上游库区公路上一高墩桥梁为例,根据提出的方法进行验算,其结果符合工程实际,具有较好的实际工程应用价值和前景,其方法和结论可以供其他同类工程参考。更多还原

【Abstract】 In the western regions of China where mudslides occur frequently,the traffic routes always need to go through the mudslides channel,the pier bridge built in the mudslides channels are easily suffered the impact of the mudslides.The methods of calculating the impact pressure are raised for designing highway and municipal bridges.This paper derives the impact pressure calculating formula of the mudslides in Lancang river upstream reservoir area with a highway high pier bridge the proposed method of calculation has the good practical application value and prospect,and can be a reference for other similar projects.更多还原
