| Abstract: | Three cast-in-situ bored piles are used as test piles to carry out the single-pile vertical compression static load experiment for the construction of a bridge on a highway. The pile's axial force transmission and lateral resistance properties were tested. The characteristic of the Q-S curve of the static load experiment, the transmission mechanism of the pile's axial force,and the performance of the pile's lateral resistance and end-bearing force are analyzed. The effect of the the borehole formation method and mud circulation on the engineering properties of the cast-in-situ bored pile are discussed. The characteristics of the bearing capacity of such pile in mudstone foundation as well as the pile's failure mechanism are found out. |
