| Abstract: | Combining three test piles of a Hanjiang River bridge,the paper studied the influence of different construction techniques on the capacity of bored piles in the condition of thick gravel layer.The results show that the hole bored in the process,mud performance,cleaning time and cleaning method will directly affect the performance of pile side friction and pile end resistance,and proposed the technical measures of improving bearing capacity of bored pile and some matters should been paid attention to. |
