Immediate Settlement - Burland Burbridge
Immediate Settlement - Burland Burbridge
(OP)
Hi, Im writing a spread sheet to calculate immediate settlement using the Burland and Burbridge formula. However Ive come across a problem with the layer thickness correction factor, f1. The equation is as follows:
f1 = H/z1.(2-H/z1)
The problem is that when H/z1 > 2, you get a negative number, which results in a negative settlement i.e. heave.
Can anyone please confirm if this formula is correct or not.
Cheers and best wishes for the New Year.

(2-H)/z1 ? Then the heave cndition does not exist.

Can you give me the link that you used to find the BB equation.

Have you considered "Peck & Bazaraa" "NAVFAC method" or "D'appolonia" Just curious to know why Burland method?
In ASCE's geotechnical special publication No. 15, D'appolonia method was most accurate between predicted versus observed settlement study.
