Settlement of Pile Group
Settlement of Pile Group
(OP)
I need to calculate the settlement of pile group I found that some geotechnical publications said based on "equivalent raft concept", the total load is carried by a "equivalent raft" located at a depth of 2/3pile length and assumed the load spread from the perimeter of pile group at a slope of 1 horizontal to 4 vertical. Below the raft the load is spread as a slope of 1 horizontal to 2 vertical. Could anyone explain how the 1:4 and 1:2 were defined.
Also I found some books does not consider the "equilvalent raft". The total load spread at a slope of 1:2 begin at the depth of 2/3 pile length. Which one is better for the calculation of pile group settlement?
