严寒地区水利工程混凝土结构冰压力影响研究
Study on Ice Pressure Effect of Hydraulic Concrete Structure in Severe Cold Area
摘要
Abstract
The temperature deformation of ice will produce thrust and drawing force on the concrete structure;especially in the severe cold area,with long freezing period and great temperature gradient,it has a greater impact on the concrete structure.In this paper,based on the calculation of the ice temperature characteristics by the finite element method,a numerical simulation model of the dam under ice pressure is established in combination with a practical project.The deformation and stress of the dam are analyzed by applying ice thermal expansion force on the upstream surface of the dam.The results show that although the expansion force of ice has little effect on the de-formation and stress of the dam,the maximum deformation is 0.3 mm,the maximum static ice pressure at the ice cover is 1.5 MPa,and a tensile stress of 0.6 MPa appears at the dam heel,which should be taken seriously.关键词
