ring fault

Based on the non-similarity structure of listric faults,a configuration similarity method(CSM) is brought forward for 3D modeling of the non-similarity structure.

断层构形非相似性问题制约着三维可视化建模的发展,铲状断层表现得尤为典型。

As viewed from geomechanics, stratigraphic stress distribution in pinnate fault zone is analysed, conception of influence of unbalanced stratigraphic stress on bridge foundations is expounded, and finally design principles for bridges to span the pinnate fault zone, calculation methods for bridge foundation design and measures against the unbalanced stress are proposed.

从地质力学的角度分析了羽状断层带地层应力分布状况，阐述了不平衡地层应力对桥梁基础产生不良影响的概念，提出跨越羽状断层带桥梁设计原则，桥梁基础设计计算方法以及消除不平衡应力影响的措施。
