结构性土体破损全过程分析

The Whole Process Analysis Of Earth Body Damage in Structure

本文运用伤力学和断裂力学理论，从能量的角度对结构性土体裂纹扩展进行了全过程分析。分析结果表明，结构性土体抗剪的断裂韧度小于其抗拉断裂韧度。在土体破损分析中，若能考虑运用损伤因素的影响来评价土体的工作状态，则比较安全。

The whole flaw development process of earth body in structure is analyzed according to the theory of damage mechanics and fracture mechanics from the view point of energy. The result shows that the fracture flexibility degree of earth body to resist shear in structure is less than to pull, and it will be safer if the work state of earth body can be evaluated by the influence of damage factor in the damage study of earth body.
