| Abstract: | This paper introduces a successful application of the composite foundation with low strength piles in Jialichen Bridge in Taizhou, Zhejiang to alleviate bridge-head jumps. Through a series of tests, including field loading tests, earth pressure tests and settlement observations of the top and midpoint of piles, the paper thoroughly dealt with the bearing capacity, bearing characteristics and settlement variations of the foundation. Significant conclusions are drawn from the study, which should be useful for engineering applications and further research. |
| Keywords: | low strength pile composite foundation field test stress ratio of pile to soil bearing capacity settlement |
