The safety of high-speed railway over areas with serious regional land settlement is further concerned by more and more engineers. However, there is few research concerned about the influence on bearing behaviour of pile foundations by regional land settlement in high-speed railway bridge construction at present. This paper presents a new method using the numerical method to simulate underground water level’s annual variations in the situation of continuous pumping based on the limited site measurement data and studying the influence on bridge pile foundations by regional land settlement on that basis, finally obtaining the relationship between regional land settlement and bridge pile foundation settlement. The result shows that increase of land settlement lags behind pumping due to soil creep effect, in early phase the land settlement is mainly affected by the consolidation of soil mass and in late phase affected by creep. The associative relationship of regional land settlement and bridge pile foundation settlement is very obvious which generally expresses as a logarithmic form.
