- Abstract
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.
