The Analytical Method for The Experimental Data of the Laterally Loaded Piles in Multiple Layers of Soil

This paper, based on the data of field experiment of steel piles at Zheng-Kiang port, proposed a new method for analytic calculation and a new concept for the curves of the subgrade coefficient. It not only provides a practical method for studing sub-grade coefficient, but also has laid a foundation for studing the interaction of soil-pile structure by field data.
