摘　　要：按照黄骅盆地中区典型构造剖面设计砂箱实验模型，实验结果表明，通过砂箱实验可以有效重现构造形成的过程和序列，黄骅盆地中区新生代构造形成序列是：歧东构造带、歧中构造带、自东构造带、新港断层带，在同一构造带中断层形成的总体顺序是北倾断层略早于南倾断层。Two sandbox models were designed from a typical structural profile of Cenozoic age in thecenter of the Huanghua basin. Experiment results indicated that sandbox experiment is an effectivemethod to investigate the formation process and sequence of structures. The formation sequence ofCenozoic structures in the central part of the Huanghua basin is: (1) Qidong structural zone, (2)Qizhong structural zone, (3) Baidong structural zone and (4) Xingang fault zone. In the samestructural zone, formation of north-dipping faults is earlier than that of south - dipping faults.
