Rigid Pile-soil Interaction Research In Coastal Region Of Dongying

Dongying as a emerging city, with the rapidly developing economy, further development of coastal areas is imperative. In this region, rigid pile are commonly used to reinforce the foundation in the project, but the pile - soil interaction mechanism are rather complex. Currently, the knowledge on the stress and deformation characteristics of pile - soil are not clear, the calculation of the stress and strain are inaccurate either.This paper selects an appropriate pile - soil interface model based on the geological characteristics of coastal area in Dongying. According to theory and experience, the pile foundations for the relevant parameters are determined. The correctness of theoretical simulation are verified through the previous works, so that the appropriate adjustments and estimates in practical engineering design of the pile can be made.According to the investigated engineering geological conditions to simulate the soil, establish the model of rigid piles - prestressed concrete pipe in the practical application at the same time. On the basis of static load test site, analyze the Pile settlement and capacity of this region. The pile-soil interaction at actual project situation is simulated by two kinds of pile and soil models of ANSYS. Finally, compare the ANSYS analysis results and the field data, the result shows that the pile and the soil layer interact, the conclusions of the site analysis are basically consistent with the result of ANSYS simulation.
