摘要
通过求解平面应力的问题的有限单元方法反演了沧州河间区域构造应力场,并确定了最大住应力场和最大剪应力集中区,从而探索分析构造地裂缝的潜在危险区;建立了地裂缝二维平面模型,分析河间地区区域构造应力场以及区域应力集中区和地裂缝的对应关系。
By solving the plane should force the finite element inversion method the Cangzhou Hejian regional tectonic stress field,and determine the maximum live should force field and the maximum shear stress concentration zone,so as to explore the analysis of potential danger area of tectonic ground fissures;establish the two-dimensional plane model of ground fissure and calculation analysis in the area of Hejian regional tectonic stress field and regional stress concentration zone and fissure in the relationship.
