Conventionally, the rupture mechanism of fibre and yarn is expounded from the Angleof force loading, and their attribute indexes are expressed by rupture strength and rupture elongation.
目前对纤维和纱线断裂机理的阐述多是从受力角度考虑的，其属性指标习惯用断裂强力和断裂伸长率表示。

According to the energy theory, the formula for the passive earth pressure of retaining wall is derived, and the calculation method for the ruptureAngle is discussed.
从能量理论出发，导出任意情形下挡土墙被动土压力的计算公式，探讨破裂角的计算方法。
