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。 - 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
