FINITE ELEMENT NUMERICAL SIMULATION OF THE TECTONIC STRESS FIELD OF THE CRUST-MANTLE COMPOSITE STRUCTURAL PROFILE OF LIANYUNGANG-YINCHUAN LITHOSPHERE

    摘要
  • 摘要: 从岩石圈壳-幔组合结构出发,选择了大华北岩石围块体内一条NWW向连云港-银川的岩石圈壳-幔组合结构剖面,试图先从一个简单的力学模型开始,用二维有限元法得到岩石围(地壳和上地幔顶盖层)中的构造应力场的分布特征,从而解释板内地震与岩石围亮-幔结构比值(R)相关的力学原因。

     

    Abstract: This paper, selecting a NWW Lianyungang-Yinchuan lithosphere crust-mantle composite struc tural profile, first tried to start from a simple mechanical model to use the two dimensional finite element meth0d to obtain the distribution characteristics of tectonic stress field in the lithosphere (crust and the top layer of upper mantle), thus interpreting the mechanical cause of the correlation of the imtroplate earthquake and lithosphere crust mantle strcture rate (R).
