Abstract EN
The calculative width directly affecting the horizontal bearing capacity of the pile is an important parameter of the horizontal loaded pile foundation and its effective value will change with the variation of slope angle.
In order to research the effect of slope on calculative width, 4 groups of model test under static lateral loading with different slope angles were carried out indoor.
Based on the PIV system, the horizontal diffusion angle was obtained by the quantitative analysis of the vectorial displacement field of soil around the pile.
The calculative width of pile under 4 slopes was then calculated based on the Horizontal Diffusion Principle.
Compared with numerical simulation and full-scale test, calculative width based on Horizontal Diffusion Principle is greater than that based on the code of China (JGJ94-2008) and it decreases by about 3.3 m by every 10° increase of slope.
After correcting the calculative width based on Horizontal Diffusion Principle, m-value that can characterize the horizontal resistance of the pile is greater than that based on the code of China (JGJ94-2008); the average difference of two m-values is about 75 MN/m4.
Slope has a strong weakening effect on m-value.
These conclusions provide a certain reference for the selection of calculative width in engineering.
