摘要： 根据盆地内沉积地层与走滑活动的对应关系，将盆地内沉积划分为前走滑层序、同走滑层序及后走滑层序，应用平衡剖面技术恢复以上3种走滑层序到沉积之前的水平状态，获得了辽河盆地构造演化历史。在此基础上，通过典型平衡剖面计算不同时期的伸展量、伸展率、伸展速率等参数，定量化描述构造活动过程，探求不同地质时期构造活动对辽河盆地中部构造的影响。

Abstract: The sedimentary formation in Liaohe basin is divided into the pre?strike?slip sequence, syn?strike?slip sequence and post?strikeslip sequence, according to the relation between the sedimentary formation and the strike?slip activity in the basin. The balanced cross section method is applied to initialize the three strike?slip sequences to the horizontal state before depositing and obtain the structural evolution history of Liaohe basin, based on which the typical balanced cross section is used to calculate the parameters about the magnitude, the percentage and the rate of the structural stretching in the different geologic times, so as to quantitatively describe the structural evolution process and investigate or appraise the effect of the structural events in different geologic times on the structures in the center of Liaohe basin
