coulomb failure criteria meaning in Chinese
库仑破坏准则
Examples
- The basal specialty of this method is just to consider static equilibrium and mohr - coulomb failure criterion of soils
它的基本特点就是，只考虑静力平衡条件和土的摩尔?库仑破坏准则。 - In this paper , systematic numerical test have been carried out to study the stability of surrounding rock mass with different distribution of weak interbed , different distance between weak interbed and limit of excavation , different thickness of weak interbed , in the different confining coefficient and representational surrounding rock mass graded ii , iii , iv . all of the numerical modeling is plain - strain type with elastic - plastic constitutive law and mohor - coulomb failure criterion , through the integrated numerical analysis program final . plentiful numerical test results have been drawn via analyse the deformation , tensile stress region , plastic region of surrounding rock and the stress status of shot - crete
大量的工程实践表明，软弱夹层对地下洞室围岩稳定性的影响有着决定性的作用，本文以大型数值仿真分析系统final为平台，采用弹塑性应力应变关系和m - c屈服准则建立平面应变问题有限元模型，对软弱夹层的分布部位、分布距离、软弱夹层的厚度对围岩稳定性的影响以及在具有不同侧压力系数的地应力场中和、 、类代表性围岩中软弱夹层对围岩稳定性的影响进行了系统的数值试验，研究得出了软弱夹层对围岩位移、拉应力区、塑性区以及喷射混凝土层内力等影响丰富的量化成果，以便直接为工程设计人员提供参考。
