layer of concrete
Examples
- Concrete pavements - part 2 : test methods for the determination of the bond between two concrete two layers
混凝土路面.第2部分:两个混凝土层间的粘结测定的试验方法 - The investigation results show that fly ash particles serve as nucleation sites for the growth of the hydration products and the quality of fly ash does not affects the microstructure of concrete much
研究结果表明：粉煤灰颗粒充当水化物的中心质，掺加粉煤灰使混凝土层状形貌得以改善，孔隙下降，不同品质粉煤灰对早期水化物的生成有明显的影响。 - In the layered model , transverse shear is ignored and material is assumed to be in a state of plane stress , and some other presuppositions are introduced , such as cracking of concrete takes place only in the plane perpendicular to the normal
但是钢筋混凝土板的非线性有限元研究目前一般都是采用分层法，将板分成若干混凝土层和钢筋层，忽略横向的剪切影响，各层混凝土材料按平面应力状态处理，这与真实情况有区别。 - 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。
