摘　　要：对拉林铁路扎绕特大桥进行桩基承载力试验。运用自平衡法测试桩基极限承载力,测出桩基极限侧摩阻力以及极限端阻力。根据试验结果,结合地勘资料与设计资料,对桩长与桩径进行优化设计。通过现场试验,获得该卵石地区极限侧摩阻力和极限端阻力,以供该地区其他工程借鉴使用。The pile bearing capacity experiments were conducted on Zharao Bridge of the Lalin Railway. The ultimate bearing capacity of the pile is measured by the self-balance method, and the ultimate lateral friction resistance and the ultimate resistance of the pile are measured.Based on the results of the test and combined with the geological prospecting data and design informations,tthe optimum design of pile length and pile diameter is made.Based on the field test, the ultimate side friction resistance and the ultimate end resistance of the gravel area are obtained, the experience could be used for other projects in this area,which is for reference for other projects in this area.
