| 摘 要： | 根据黄骅盆地实际情况设计系列砂箱实验模型。基于实验结果分析，笔者认为黄骅盆地是近Ｓ—Ｎ 向伸展形成的新生代裂陷盆地。盆地内部不同方向的断层形成于同一伸展变形过程。导致盆地内部断层方向复杂多变的原因是盆地裂陷边界方向的变化， 而非走滑构造或拉分作用叠加的结果。实验模型同时也可较好地用以解释整个渤海湾盆地区新生代构造的成因。

| Abstract: | A series of plane sandbox experiments, designed after the actual conditions of the Huanghua Basin, were conducted. According to the results of simulating results, the Huanghua Basin is interpreted as a Cenozoic rift caused by anextensional deformation in a nearly S—N direction. Faults of different orientations in this basin were caused by the same extensional deformation. The origin, which caused the faults of complex variations in orientations, is the change of the Basin's boundary direction, but not the superposition of strike-slip or pull-apart deformations. The experimental models are also can be used to the interpretation for mechanisms of Cenozoic tectonics in the whole Bohai Bay Basin. |
