Solution collapse breccia pipes (SCBPs), that form under the influence of gravity, and sinkholes were studied on the Colorado Plateau in Arizona, USA to identify preserved evidence of their formation mechanisms. Close range photogrammetry was employed for data acquisition and reconstruction of the three‐dimensional (3D) scene of the outcrops. Key geological features were accurately mapped within their true 3D space using photogrammetry. Interpretations of the results suggest that the mechanisms controlling the collapse, and its debris distribution within the pipe, are influenced by in situ discontinuities in the host rocks at every scale from the regional context to the size and shape of the collapsed blocks.

摄影测量学在美国科罗拉多高原溶液倒塌角砾岩管道测绘中的应用

在美国亚利桑那州的科罗拉多高原上研究了在重力作用下形成的溶液倒塌角砾岩管道（SCBP）和下沉孔，以发现其形成机制的保存证据。近距离摄影测量法用于露头的三维（3D）场景的数据采集和重建。使用摄影测量法可将关键的地质特征准确地映射到其真实的3D空间中。结果的解释表明，控制坍塌及其在管道内的碎屑分布的机制受到了从区域环境到塌陷块的大小和形状的各个尺度上的主岩原位不连续性的影响。
