Abstract

 

     Through comparing the finite element analysis value with experimental value, it is determined that failure states of soil surrounding the pile and at top and bottom of reamed disc under the vertical tension. According to the punching theory and the slip theory, the computing model of the uplift bearing capacity of the concrete pile with expand-reamed disc is analyzed. The mechanical computing model under soil’s punching failure and sliding failure is respectively calculated. The above-mentioned analysis is to be laid to further determine concrete pile with expand-reamed disc uplift bearing capacity.
