Mechanical state analysis of different variants of piled rafts
DOI: 10.3846/bjrbe.2015.01
 
Traditional raft design methods describe unpiled and fully piled rafts. The current paper aims to discuss intermediate raft design variants when the raft is at the same time partially supported by piles and partially rests on the ground. The loading conditions of all variants as well as mechanical properties assumed to be identical, general numerical simulation assumptions are also the same. The task is to analyse the stress and strain state of the raft for all variants (unpiled raft, partially piled raft, fully piled raft), to compare the results and to determine the most rational case. Raft settlements, bending moments and expenses of the materials are compared on the basis of the results.
 
Keywords: piled raft, soil–raft interaction, variants, finite element analysis, design.
