文中构建了两组构造物理实验，对存在先存被动盐底辟构造的含盐盆地的厚皮挤压构造演化特征进行模拟，研究揭示了库车坳陷西段秋里塔格构造带新生代盐相关构造演化过程。实验结果表明，同构造沉积速率对库车坳陷西段秋里塔格构造带博孜—却勒区域（西段）和秋里塔格—克拉苏区域（东段）盐相关构造横向分段差异变形具有重要的控制影响作用。在挤压过程中，博孜—却勒区域慢速同构造沉积使得先存被动盐底辟北翼（拜城凹陷南翼）向南逆冲到底辟南翼之上，并促使却勒盐推覆体和米斯坎塔克盐背斜形成；而秋里塔格—克拉苏区域快速同构造沉积使得先存被动盐底辟北翼快速下沉，而其南翼在挤压应力作用下向北逆冲到底辟北翼（拜城凹陷南翼）之上，形成南秋里塔格盐背斜。

Two scaled analogue models are constructed to simulate the evolution of thick-skinned shortening on salt-bearing basins with pre-existing passive salt diapirs. These models simulate the evolution of the Cenozoic salt-related structures in the Qiulitage structural belt, western Kuqa depression. Model results show that the syn-kinematic depositional rate has a major controlling influence on the differential structural deformation in different longitudinal segmentations from the Bozi-Quele area (the west part) to Qiulitage-Kelasu area (the east part) in the Qiulitage structural belt, western Kuqa depression. During the shortening, the slow syn-kinematic depositional rate caused the north flank (the south flank of the Baicheng sag) of the pre-existing passive salt diapir thrust onto the south flank (the north flank of the Misikantake salt anticline) and made the formation of the Quele salt nappe and the Misikantake salt anticline in the Bozi-Quele area;In contrast, the quick syn-kinematic depositional rate caused the south flank of the pre-existing passive salt diapir thrust onto the north flank (the south flank of the Baicheng sag), which made the formation of the south Qiulitage salt anticline in the Qiulitage-Kelasu area.
