This paper is a study of the settlement behaviour and prediction of pile foundations of Beijing-Shanghai high-speed railway due to bridge construction loads. Field test results showed that the structure would bear the loads imposed by the bridge. The settlement analysis is used in this paper with new modification. In the analysis, the effects like compression modulus, soil stress, soil pile interaction and pile length are considered. The calculated results of the pile settlement are compared with that measured in the field monitoring. The results provide insight to the settlement analysis of pile groups in soft clayey soils and can be a useful tool to analysis other types of soils. In this paper, the norms analysis are developed using a proposed empirical equation to calculate the compression modulus from that tested under pressure 100 to 200 kPa which modify the results of the settlement analysis and become close from the reality. Finally, the analysis produced logical and conservative results using a proposed empirical equation besides to the new field measuring technique using single-point settlement and liquid level gauge to calculate the thickness of compressed layer which is considered as a difficult task in the field. This scenario can be applied to the similar problems in the deep soft soils.
