Supplement to: The influence of detachment strength on the evolving deformational energy budget of physical accretionary prisms

Tracking the evolution of the deformational energy budget within accretionary systems provides insight into the driving mechanisms that control fault development. To quantify the impact of these mechanisms on overall system efficiency, we estimate energy budget components as the first thrust fault pair develops in dry-sand accretion analogue experiments.
This data set includes photos taken and forces measured in four experiments performed at Université de Cergy-Pontoise in October-November 2016. The experiments are described in McBeck et al. (submitted).
The data are organized into 5 main folders, with the following contents:1) E373_photos: Contains 3 subfolders: droit_RDY, gauche_RDY, haut_RDY. Each subfolder contains images taken at 1 second intervals throughout experiment. droit_RDY, gauche_RDY, and haut_RDY contain photos of the right, left, and top of the sandpack.2) E374_photos: Same organization and contents of folder E373_photos3) E375_photos: Same organization and contents of folder E373_photos4) E376_photos: Same organization and contents of folder E373_photos5) forces: Contains text files that list the normal force against the backwall (N) and total applied normal displacement to the backwall (mm) in the second and first columns, respectively. The filename indicates which experiment the text file describes.

追踪增生系统内部的变形能量收支演化过程，可为揭示控制断层发育的驱动机制提供关键认知。为量化上述机制对系统整体效率的影响，本研究在干砂增生类比实验中，当第一组逆冲断层对发育时，对能量收支各组分进行了估算。
本数据集包含2016年10月至11月在塞吉-蓬图瓦兹大学（Université de Cergy-Pontoise）开展的4组实验的拍摄照片与实测力学数据，相关实验细节详见McBeck等（已投稿）的研究成果。
数据集共分为5个主文件夹，具体内容如下：
1) E373_photos：包含3个子文件夹droit_RDY、gauche_RDY、haut_RDY。每个子文件夹内存储了实验全程以1秒为间隔拍摄的图像，其中droit_RDY、gauche_RDY、haut_RDY分别对应砂箱右侧、左侧与顶部的拍摄照片。
2) E374_photos：组织结构与内容与E373_photos完全一致。
3) E375_photos：组织结构与内容与E373_photos完全一致。
4) E376_photos：组织结构与内容与E373_photos完全一致。
5) forces：包含若干文本文件，文件中第二列与第一列分别记录了后壁受到的法向力（单位：牛[N]）与施加于后壁的总法向位移（单位：毫米[mm]），文件名标注了该文本文件对应的实验编号。
