Based on the field test, the development of pressure and settlement above pile cap and soil surface are obtained. Test results indicate that both relative settlement and pressure ratio vary with the filling before the height of embankment is less than 0.9 m, after which the relative settlement tends to be stationary while pressure ratio keeps rising till the end of filling and becomes steady quickly in standing period. Furthermore, the numerical simulation is adopted to analyse the influence of pile cap coverage ratio on settlement and pressure distribution in the single pile processing area. Results show that enlarging the diameter of pile cap can improve the settlement stability of soil between piles remarkably, while narrowing pile distance can reduce the settlement of soil effectively.
