Micropile Lifetime
The micropile lifetime is introduced by reducing the area of the reinforcing pipe or rod using the loss of thickness due to corrosion of the steel section re and coefficient Fut taking into account the connection of the micropile and the surrounding soil.
where: | D | - | external diameter of reinforcement (pipe or rod) |
t | - | wall thickness of reinforcing pipe | |
Fut | - | coefficient taking into account the connection of micropile and surrounding soil (0,5 -1,0) | |
re | - |
