The guild pile structure is an important anchorage form.The current code has not detailed the rules of wind load and wave load of marinas.In order to improve the calculation and analysis of the guild pile of marinas,we analyze the force of guild piles under wind load and wave load by ANSYS finite element software.We put forward reasonable suggestions on the calculation of the guild pile of marinas,and recommend that the integral model should be used in the calculation of marinas.The shielding effects of wind load should be considered such as ship type,the wind height of building,ship spacing,etc.
