摘　　要：本文根据大量试验和国内外资料分析结果 ,提出混凝土及钢筋混凝土局部承压工作机理和破坏机构 ;建立混凝土及钢筋混凝土局部承压的强度理论———楔劈理论 ;In this paper,based on a lot of testing and analyzing results at home and abroad,working principle and failure mechanism of concrete and reinforced concrete are put forward,strength theory—wedge cleaving theory of local pressure of concrete and reinforced concrete are set up,and calculation formula and simplified calculation method of local pressure strength are developed according to extreme balance principle.

关 键 词：混凝土 钢筋混凝土 局部承压 工作机理 楔劈理论
