Analysis Using the Compression Constant
The equation to compute compression of an ith soil layer below foundation having a thickness h arises from the definition of compression constant C:
where: | σor,i | - | vertical component of original geostatic stress in the middle of ith layer |
σz,i | - | vertical component of incremental stress (e.g. stress due to structure surcharge) inducing layer compression | |
hi | - | thickness of the ith layer | |
Ci | - | compression constant in the ith layer |
The program allows for inputting either the compression constant Ci or the compression constant C10 (the program itself carries out the transformation).
