Contributions of rock mass structure and fragmentation to the emplacement of rock avalanches: insights from laboratory experiments

This data set provides a movie of D1 recorded using high-speed camera during experiments, which can be useful for a thorough understanding of the evolutions of internal rock damages The calculated data of area covered by deposit, the travel distance of the center of mass on the horizontal plane, the travel distance of sliding mass on the horizontal plane, and the relative breakage ratio are also provided. In addition, we also provided the data of velocity profiles of blocks with different structures at t=0.1 s from x=0 m to x = 0.8 m. Movie S1. The sliding and fragmentation process of D1. Data Set S1. Data of area covered by deposit, the travel distance of the center of mass on the horizontal plane, the travel distance of sliding mass on the horizontal plane, and the relative breakage ratio. Data Set S2. Data of velocity profiles of blocks with different structures at t=0.1 s from x=0 m to x = 0.8 m.本数据集提供了实验过程中通过高速摄影机录制的D1试样影像，可用于透彻理解岩石内部损伤的演化过程。同时还包含如下计算数据集：堆积体覆盖面积、质心水平位移距离、滑体水平位移距离以及相对破碎率（relative breakage ratio）。此外，本数据集还提供了t=0.1秒时，x方向0米至0.8米范围内不同结构块体的速度剖面数据。 附： S1视频：D1的滑动与破碎过程 S1数据集：堆积体覆盖面积、质心水平位移距离、滑体水平位移距离及相对破碎率计算数据 S2数据集：t=0.1秒时x方向0米至0.8米范围内不同结构块体的速度剖面数据
