摘要
Abstract
Taking the Dongzhang reservoir project as the research background,a numerical model of a non-overflow concrete gravity dam was established to systematically analyze the pore water pressure,stress distribution,and displacement characteristics of the dam under different operating conditions.The results show that with increasing water level,the pore pressure gradient becomes steeper,and uplift pressure significantly increases under the check flood level.Horizontal stress increases from the base toward the dam crest,while the maximum vertical stress expands toward the middle section at high water levels,indicating a broader influence range of uplift pressure.In terms of deformation,the maximum horizontal displacement occurs at the dam crest,while the maximum vertical displacement appears at approximately one-third of the upstream dam base.Higher water levels correspond to larger displacements.关键词
