secondary stress field meaning in Chinese

次生应力场

Based on the simplified structure of rock mass , flac ( superscript 3d ) numerical modeling technique is used to systematically analyze the distribution features of the secondary stress field , strain field and plastic zones in the surrounding rock mass of the underground cavities after the excavation
摘要在岩体结构模型概化的基础上，采用flac (上标3d )数值分析方法，系统研究了澜沧江某大型水电站大跨度、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 : taking the underground powerhouse in a huge hydropower station as an example , the authors studied distribution pattern of the secondary stress field of surrounding rock mass with nonlinear finite element method of the large - spaned underground powerhouse with high side wall and evaluated the stability of surrounding rocks
文摘:以某大型水利工程拟建地下厂房为典型实例，应用二维非线性有限元分析方法，研究大跨度、高边墙地下厂房区二次应力场分布规律，并评价围岩的稳定性。
