Data for: Investigating the softening of weak interlayers during landslides using nanoindentation experiments and simulations

Three shale samples are immersed in water for different immersing time t (t=0days, 1day, 3days, 5days, 10days). Then these samples are tested using the nanoindentation experiment with Berkovich indenter and Cube Corner indenter. The indentation grid of Berkovich indenter consists of 225 indentations, and the indentation grid of Cube Corner indenter consists of 100 indentations. The data includes the elastic modulus and hardness measured by Berkovich indenter, as well as the hardness measured by Cube Corner indenter.本数据集的试验流程如下：将3块页岩试样置于水中开展不同时长的浸泡处理，浸泡时长t分别为0天、1天、3天、5天、10天。随后采用伯科维奇压头（Berkovich indenter）与立方角压头（Cube Corner indenter）对上述试样进行纳米压痕试验，其中伯科维奇压头的压痕网格包含225个压痕点位，立方角压头的压痕网格则包含100个压痕点位。数据集涵盖伯科维奇压头测得的弹性模量与硬度数据，以及立方角压头测得的硬度数据。
