Abstract. This article describes an innovative, complex and affordable monitoring system designed for joint observation of environmental parameters, rock block dilatations and temperature distribution inside the rock mass with a newly designed 3-meter borehole temperature sensor. Global radiation balance data are provided by pyranometers. The system introduces a novel approach for internal rock mass temperature measurement, which is crucial for the assessment of the changes in the stress field inside the rock slope influencing its stability. The innovative approach uses an almost identical monitoring system at different sites allowing easy setup, modularity and comparison of results. The components of the monitoring system are cheap, off-the-shelf and easy to replace. Using this newly designed system, we are currently monitoring three different sites, where the potential rock fall may endanger society assets below. The first results show differences between instrumented sites, although data time-series are relatively short. Temperature run inside the rock mass differs for each site significantly. This is very likely caused by different aspects of the rock slopes and different rock types. By further monitoring and data processing, using advanced modelling approaches, we expect to explain the differences among the sites, the influence of rock type, aspect and environmental variables on the long-term slope stability.

观察岩石边坡的热状态，并结合裂缝计稳定性监测

摘要。本文介绍了一种创新，复杂且价格合理的监测系统，该系统旨在通过新设计的3米井眼温度传感器联合观测环境参数，岩块膨胀和岩体内部的温度分布。总辐射平衡数据由总辐射表提供。该系统引入了一种用于内部岩体温度测量的新颖方法，这对于评估影响其稳定性的岩质边坡内应力场的变化至关重要。该创新方法在不同站点使用几乎相同的监视系统，从而可以轻松设置，模块化和比较结果。监控系统的组件价格便宜，现成且易于更换。使用这个新设计的系统，我们目前正在监视三个不同的站点，潜在的岩石崩塌可能危及下面的社会资产。最初的结果显示了仪器站点之间的差异，尽管数据时间序列相对较短。岩体内部的温度随每个地点的不同而显着不同。这很可能是由岩石坡度的不同方面和不同的岩石类型引起的。通过进一步的监视和数据处理，使用先进的建模方法，我们希望能够解释站点之间的差异，岩石类型，纵横比和环境变量对长期边坡稳定性的影响。这很可能是由岩石坡度的不同方面和不同的岩石类型引起的。通过进一步的监视和数据处理，使用先进的建模方法，我们希望能够解释站点之间的差异，岩石类型，纵横比和环境变量对长期边坡稳定性的影响。这很可能是由岩石坡度的不同方面和不同的岩石类型引起的。通过进一步的监视和数据处理，使用先进的建模方法，我们希望能够解释站点之间的差异，岩石类型，纵横比和环境变量对长期边坡稳定性的影响。
