Study on the strength influence of pile driving disturbance on the surrounding soil

Abstract

The research on the strength influence of pile driving disturbance on the surrounding soil on marine environment is very less. This article is an actual pile driving project in the sea, the soil samplings with different distance from pile was taken and some laboratory test was done, the influence of soil property when pile driving is founded. According to the experimental results, the shear stress parameter and unconfined compressive strength index of soil in the hole increased with the increase of drilling depth, and the unconfined compressive strength index of soil in the hole nearly returned to the level of undisturbed soil 39 days after piling.
