摘要
Abstract
Taking the project of Hongjiadu CFRD as an example, on the base of nonlinear DFuncanchang 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 deformation calculation and comparison.Results showed than the influence of the mporary section retaining water dam deformation and stress of completion period is limited, using provisional cross-section retaining water flood construction scheme is feasible.关键词
