| Abstract: | Taking the project of Hongjiadu CFRD as an example,on the base of nonlinear DFuncan-chang E-B model,the paper established the finite element model.By using midpoint incremental method,aim at the two conditions of whether to use temporary section retaining water in construction period,discussed the temporary section retaining water for dam deformation and stress influence under the conditions of dam completion period stress deformation and stress influence under the conditions of dam completion period stress... |
| Keywords: | CFRD temporary cross-section water retaining stress-strain non-linear |
