摘　　要：三维构造建模及恢复是验证构造解释在三维空间的合理性和一致性,更重要的是构造复原技术能建立断裂体系的形成过程,恢复应力场轨迹,进而获得裂缝类型与分布模型。在Gocad平台上进行构造模型及恢复实验,面模型恢复的结果表明,大邑背斜恢复应力分布图的最大主应力方向为北西-南东向,这证明了印支晚期以来北西-南东的挤压作用,相关指数为分析潜在裂缝提供依据。这一方法适用于小范围的研究区来预测裂缝类型和分布。Three-dimensional structural modeling and restoration is a technique which is used to verify the rationality and consistency of the structure interpretation in three dimensional spaces. More importantly, the structural restoration technology can help us establish the formation of fault system and restore the trajectory of stress failed, and then get cracking types and distribution model. It establishes structural modeling and SGrid with Gocad platform, and then to restore. Dayi anticline recovery stress distribution of the maximum principal stress direction is northwest- southeast, which proves the North West - South East compression since the late Indo-China epoch. The related indexes provide the basis to analyzing the potential crack. This method is appling to small area to forecast the crack type and the distribution.
