通过数值分析，模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场，结果表明：研究区主应力方向为北东～南西向，第二期的构造扭动使其由北向东发生了一定的偏转，但总的方位变化不大；O〓～S～D时期，塔中地区构造运动较强，研究区大部分处于高应力状态，岩石破裂程度较高，而岩芯观察结果也证实了这一结果，即O〓灰岩地层中早期形成的构造结构面比较发育，单个结构面的规模也较大；C～P时期，岩石的破坏程度较早期有所提高，主要表现在两个方面，一是各局部区岩石的破坏程度普遍有所提高；二是各个级别破裂区的分布范围相应地扩大了；研究区应力分布表现出明显的不均匀性，特别是剪应力，无论是O〓～S～D时期，还是C～P时期，都有很大的差异性，特别是在小断层的端部，剪应力比较集中，而且在断层的两盘，剪应力方向和大小都变化极快。
