以中俄原油管道漠大线林区伴行公路为工程背景，对公路桥梁的基桩进行了静载试验，试验采用自平衡测试方法，设计了四根试桩，并结合《公路桥涵施工技术规范》及单桩自平衡静载测试技术，进行分级加载，结果表明，公路沿线桩基土层所提供的侧摩阻力及桩端阻力充足，试桩承载力均能够满足设计要求，自平衡测试方法准确可靠。%Taking the road along forestry areas of Mohe-Daqing Railway of Sina-Russian crude oil pipeline as the engineering background,the pa-per undertakes the static loading experiments on the foundation pile of the roads and bridges by adopting the self-balance test method for four trial piles in the design,undertakes the gradation loading by combining with Construction Technical Regulation for Roads and Bridges and self-balance static test technique of single piles,and proves by the experiment result that the side friction and pile end resistance at the pile foundation layers on roads are sufficient and the loading capacity of the piles meet the design demands with accurate and reliable self-balance test methods.
