本文根据大量试验和国内外资料分析结果,给出了混凝土局部承压强度的变化规律及影响因素;提出了混凝土局部承压工件机理和破环机构;建立了混凝土局部承压的强度理论——楔劈理论,并根据极限平衡原理导出了局部承压强度满意的理论公式和建立了实用计算方法。 Based on a large number of tests and analysis results of domestic and foreign data, this paper gives the variation law and influencing factors of local compressive strength of concrete, puts forward the mechanism of partial pressure bearing on concrete and the mechanism of breaking the ring, and establishes the strength theory of local concrete pressure- Wedge theory, and based on the principle of limit equilibrium derived a satisfactory theoretical formula of partial pressure strength and established a practical calculation method.
