| Abstract: | Static loading test on the part of micro pile of horizontal load bearing at the construction site com- pares horizontal load bearing characteristics of micro piles of different length and bending rigidity. A numerical simulation analysis has been made of the influence of the principal factors such as pile diameter, pile modulus, etc, on micro pile horizontal load bearing characteristics, which can lead to a conclusion that micro pile horizon- tal load bearing capacity can be improved through appropriate choice of pile length, pile diameter and properly inserting piles in the steel pipes. |
