%X 结合检测工况对测试数据的影响，对自平衡“精确转换法”进行改进，提出摩擦桩位移协调转换法和嵌岩桩的荷载协调转换法，实际应用结果说明两种转换方法合理。所得测试结果表明湄公河大桥桩基承载力符合设计要求；分析湄公河大桥试桩的侧摩阻力和端承力分布，嵌岩桩和摩擦桩纵向承载均以侧阻力为主。<br>Based on the impact of detecting condition on testing data,the self-balanced "exact conversion method" was improved. And friction pile displacement coordinate conversion method and loads coordinate transformation method of rock-socketed piles were proposed. The results illustrated that the practical application of the two conversion methods were reasonable and Mekong Bridge pile foundation met the design requirements. Analyzing the lateral friction and end bearing force distribution of tested pile,the results show that,similar to friction piles,the main vertical bearing capacity of rock-socketed piles were the main lateral friction in the Mekong Bridge.
