摘要:

详细分析了应力场数值模拟与物理模拟的实验过程,对比两技术之间实验条件、模型转换、实验结果等方面具有的优势及适用条件,提出两者相结合进行构造成因机制分析的方法,并以高邮凹陷南断阶为例进行了说明.研究认为:数值模拟与物理模拟技术具有各自的优势,前者得到的是变形初期的应力分布结果,主要用于成因解释和变形预测,而物理模拟成果主要反应整个变形过程的构造演化;南断阶的断层分布范围受张应力控制、断层走向受剪应力影响,竹墩和许庄地区具有相似的应力分布和断层形成顺序,故断层组合及成因相似,断裂带由张应力作用产生的NE向断层及张剪应力作用下产生的NNE向、EW向共轭断层共同组成.

Abstract:

Based on the detailed analysis of structure physical modeling and numerical simulation experiments, also, comparison of the advantages and applicable conditions of the two experiments from experiment conditions, model transfer, to experiment results, this paper provides a method to analyze structure genetic mechanism using both two techniques by taking south fault terrace in Gaoyou sag for an example. It was concluded that numerical simulation gained the distribution of stress in the early stage of transformation aiming at genetic explanation and transformation prediction while physical modeling reflecting the structural evolution of the all transformed stages. Furthermore, it was studied that distribution of faults in the south fault terrace were controlled by extensional stress and the strike of faults were dominated by shear stress, and because of the similar stress distribution and faults formed order, combination of fault and genetic mechanism were also similar in the Zhudun area and Xuzhuang area, and the fault zone were composed by faults with NE strike generated by extensional stress and conjugated faults with NNE, EW strike generated by tensional-shear stress.
