Abstract

Abstract

In order to overcome the shortcomings of determining the raft thickness of a pile-raft foundation traditionally,a complete method of determining the thickness of a raft can be obtained by the following steps:It is proposed that a method in which the thickness of a raft can be determined first in accordance with the limit state of normal service and is then checked according to the limit state of bearing capacity,and the basic factors influencing the raft thickness in the two limit states are analyzed,the simplified formulas of estimating the raft thickness,external force and resistance of two-way shearing are given by combining the plate theory,coworking of the pile-raft foundation and superstructure,strut-and-tie theory of pile cap punching as well as project experience,the calculative examples and other methods to determine raft thickness are also discussed.
- pile-raft foundation,
- raft thickness,
- limit state of normal use,
