b. Load capacity under the ground:
Where:
Ru: ultimate load bearing capacity of the soil cement pile
RPU: tip-term load capacity of soil cement pile
τdi: extreme friction
hi: thickness distribution factor
L: Pile perimeter reinforced
tip Load capacity limit depends on the type of land
left Land:
Where: is the average SPT 1d and 1d below pile tip over.
Land adhesive:
Where: c is the cohesion of the ground
Friction the sides of the pile calculated by the following formula:
: for loose soil
for sticky soil
Load capacity allows for case-reinforced piles single work:
Load capacity cement soil piles determined by the joint work of Contacts piles:
Where:
qd: ultimate load capacity under soil cement pile tip Nc, Nq, Nγ: load capacity factor : bottom of foundation soil density q: load hip c: adhesive force of soils right at the bottom of nail Ab: block foundation bottom area convention di: extreme friction block circumferential conventional hi: the thickness of layer of elements Ls: perimeter blocks convention Load capacity of the entire household neck:
