次应力 meaning in Chinese
secondary stress
Examples
- 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。 - According to the feature of base reaction and base settlement , the influence of soil treatment to maximum settlement and differential settlement of foundation as well as internal force of foundation have been computed and analyzed with the finite element method
摘要针对实际工程中基底反力的分布特点和基础沉降特征，用有限元方法，计算分析得出：当地基加固后，筏板下地基呈现中心刚度大，而边缘刚度小时，可以有效减小差异沉降，继而减小由于沉降差异而引起的基础次应力。 - Due to exceedingly flat arched vault of the flat tunnel with outsized span and renewed stress allocation in surrounding rock after excavation , which would inevitably induce some excessively large load on the base of arch , therefore , larger load - bearing capability in the is " foundation is a must . on the other hand , smooth face explosion must be applied to excavation of the arch base to further ensure the integrity and continuity of country rock around tunnel
特大跨超浅埋隧道拱部结构过于扁平，开挖后发生二次应力分布，拱脚处的应力过大，要求有较大的地基承载力，拱脚开挖时必须采用光面爆破，保证围岩的完整性和不受扰动，开挖后及时封闭，防止该处积水软化围岩。 - The numerical example shows that if we use the correct guess integral , this method will give right answer . it has good performance for both p - version and hybrid stress fem . last , a hybrid stress finite element with second stress completion is presented , which keeps the virtue of normal hybrid finite element , especially good for incompressble material , because it can avoid the self lock of displacement and instability of stress results
第一部分还首次提出了一个满足二次应力完备的杂交应力单元，它的应力满足二次应力完备，而且通过巧妙的应力插值函数，避免了一般杂交应力元的矩阵求逆过程，而通常这个求逆过程都是很耗时的，这个二次应力完备杂交元保持了一般杂交元的优点，对于不可压缩问题具有较好的性能。 - 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。
