在这项研究中，我们提出了一个基于温度的评估和缓解方法，深层次的滑坡，可以预测的行为的幻灯片，并评估其稳定性。建议的方法是通过现场监测和实验测试相结合的埃尔福尔滑坡（安道尔），其剪切带材料是志留系页岩进行验证。热控和速率控制三轴试验表明，这种材料是热敏感和速率敏感，并结合现场数据，他们验证了理论假设，通过测量一个活动的滑坡的基底温度，我们可以量化和减少模型的参数的不确定性，并充分监测和预测的响应选定的深层次滑坡。这封信的数据和结果表明，所提出的模型可以给出阈值，可用作预警评估和缓解工具。
In this study, we suggest a temperature-based assessment and mitigation approach for deep-seated landslides that allows to forecast the behavior of the slide and assess its stability. The suggested approach is validated through combined field monitoring and experimental testing of the El Forn landslide (Andorra), whose shear band material is Silurian shales. Thermal and rate controlled triaxial tests have shown that this material is thermal- and rate-sensitive, and in combination with the field data, they validate the theoretical assumption that by measuring the basal temperature of an active landslide, we can quantify and reduce the uncertainty of the model's parameters, and adequately monitor and forecast the response of the selected deep-seated landslide. The data and results of this letter show that the presented model can give threshold values that can be used as an early-warning assessment and mitigation tool.
