摘要
对发育于川东北一背斜内部,并与其无成生联系、方向不同的构造特征、复合关系及其力学成因机制进行了较系统分析、论述。在此基础上对其成生时应力场最大主应力、最大剪应力和应变能进行了有限单元计算。指出了这种构造对石油天然气等矿产的控制作用。
In this paper the systematic discussion and analysis of structural feature, compounding rela-tionship and causal mechanism are conducted to the structures which developed inside an anticline andhad no genetical relation with it. Based on the above, the calculation of the maximum main stress, the maximum shear stress andthe strain energy is made with finite-element method. Finally the effect controlling the oil and gas re-sources is illustrated.
