Sand samples laboratory investigations from Heerlen landslide experiment

During a set of experiments for monitoring landslides, slope failures were triggered sequentially by undercutting the slope toe with a mechanical excavator. The laboratory investigations made on sampled extracted from the test location are here reported. Details of the experiment can be found in Chapter 5 of the PhD thesis: 'Sand slope failures: experimental and numerical advance'.在一组用于滑坡监测的实验中，研究人员通过机械挖掘机对坡脚进行掏蚀，依次触发了边坡失稳破坏。本文报告了对试验现场采集的试样开展的室内试验研究。本实验的详细内容可参阅博士学位论文《砂质边坡失稳：试验与数值进展》的第5章。
