Design
-
Check the depth of excavation
Assume layers and positionCheck earth pressure of each
layer by the excavation depthPlan design of IPS
-
Consider the location of the slab of
the structure in sectional viewUse earth pressure analyzing
Program such as SUNEX, Geo-X
-
Plan of IPS Wale
1. Install 10-15cm apart from the wall (Consider backfilling space)
2. Check minimum space of non
reinforced wale3. Decide the length of IPS wale
by earth pressure -
Plan of Strut
1. Design by load distribution width of earth pressure
2. Check column number of strut
by earth pressure3. Design considering preloading
(Check the number of preloading jack) -
Plan of Post Pile
1. Post Pile arrangement considering strong axis buckling
2. Cover plate arrangement considering weak axis buckling
3. Design considering interference of column and beam
4. Design strut and other stiffener
