塑性破坏 meaning in Chinese
ductile fracture
ductile rupture
plastic collapse
plastic failure
Examples
- Non - ductile fracture
无塑性破坏 - Its displacement could reduced to 40 percents at vault and 34 percents at floor in the condition of support , especially in the condition of cable support
在拱顶和底板以张性破坏为主,而在拱腰和墙脚以剪切破坏为主。喷层对围岩塑性破坏的限制作用显著。 - For impervious layer , the anti - inrushing stability of the pit is analyzed from the plastic damage of soil , but for semipervious layer , the anti - inrushing stability of the pit is analyzed from the seepage damage of soil
坑底为不透水层土时,应从土体发生突涌塑性破坏的角度进行分析;坑底为弱透水层土时,应从土体发生突涌渗透破坏的角度进行分析。 - Based on the simplified structure of rock mass , three - dimensional finite element numerical modeling technique is used to analyze systematically the distribution features of filed , strain field and plastic zone in the surrounding rock mass of the underground cavities after the excavation
在岩体结构模型概化的基础上,采有三维有限元数值分析方法,系统研究了大跨度、高边墙地下洞室群开挖完成后围岩的二次应力场、变形场和塑性破坏区的变化特征。 - Abstract : based on the analysis of the main causes of stope chute failure , flac3d numerical calculation software is used in the systematic study of the mechanical state of the surrounding rock before and after the chute reinforcement from the aspects of the stress distribution of rock mass , the plastic fractured region and the movement of rock mass so as to disclose the fracture mechanism of the surrounding rock and the mechanical system of the reinforcement engineering
文摘:在分析造成采场溜井破坏的主要原因基础上,应用flac3d数值计算软件,从岩体应力分布、塑性破坏区和岩体移动等方面,系统研究了溜井加固前后的围岩力学状态,揭示了围岩破坏机理和加固工程的力学机制。
