Micropile
Lizzi theory
The Lizzi method is currently the most popular method used. The root bearing capacity is provided by:
| where: | d | - | root diameter |
| l | - | root length | |
| τm | - | average limit skin friction | |
| J | - | coefficient reflecting influence of bore hole |
Coefficient J reflects the influence of the bore hole diameter – it ranges from 1,0 for hole up to 100mm and 0,8 for hole from 200mm.
Average limit skin friction of the micropile root can be found in the literature. The program contains three tables with reference values of limit skin friction. The first one is created by the program authors using various literature sources, the second one contains values of τm according to DIN 4128, and the third one includes values published in by Klein and Mišov (Inženýrské stavby, 1984). Third table contains measured values of skin friction of anchor roots for various soils, root diameters, number if groutings, etc. - using this table yields rather realistic results.
