The research on testing of spatial effect of load bearing performance of foundation pile

This paper gives a further research on spatial effect mechanism of the load bearing performance of pile.The massive position Experimental study of model test piles on site was conducted for the pile-soil interaction mechanism.The following massive precious information was obtained such as the P-s curves of the relationship between load and displacement of head of pile, each spot of pile shaft as well as pile bottom and under the static load on head of pile;the tendency of earth displacements of different soil depth of pile, and the change rule of soil displacement around the pile and so on.The test results further revealed the laws of pile-soil interaction, provided an important reference and guidance for the designs and the construction of pile foundation of housing, municipal services, path highway and bridge.
