Data Brief. 2021 Nov 17;39:107568. doi: 10.1016/j.dib.2021.107568. eCollection 2021 Dec.
This data set gives more than 11 years of temperature and displacements recorded on and in a limestone cliff. An extensive presentation of the monitoring devices and interpretation of data is proposed in Gasc-Barbier et al. (2021) [1]. The hazard-monitored zone is a perched cave in a limestone cliff where a part of its roof had collapsed. On its roof, an unstable beam reminds. A horizontal interlayer thinning from East to West, hanging to the roof of the cave at the west and east-clamped in the rock mass, delimits this remaining beam. Opened fractures can be observed all around the beam. In order to assess the remaining hazard, four fissurometers (F1 to F4) and a thermal probe were installed on the roof of the cave and two borehole extensometers (D1 and D2) were drilled perpendicular to the face of the cliff, above the cave, to understand the global behaviour of the rock mass. Measurements have been made between sockets embedded in the rock mass by means of INVAR wire measurements. Four bases made of two sockets each have been installed inside the cavity and five were put on the face of the cliff outside and above the cavity. Measurements last between January 2011 and June 2021. A 1.5-year gap is observed in the measurements because they were temporally stopped when reinforcement works were preceded carried out in the cave in order to secure the village. Thus, datasets provide more than 11 years of temperature and displacements recorded on and in the cliff, providing insight on the relation between climate and the deformation inside the rock mass. This dataset is novel because this type of data is not readily available in the literature, on the one hand, because of its length (nearly 11 years) and, on the other hand, because it is not only surface evolution of temperature and aperture but because the evolution of temperature and deformation inside the rock mass was monitored. Researchers could use these data for a better understanding of the thermomechanical coupling in rock. They could test their own modelling, constitutive laws specifically on crack propagation or thermal fatigue.
该数据集提供了11多年来在石灰岩悬崖上及内部记录的温度和位移数据。Gasc - Barbier等人（2021年）[1]对监测设备进行了广泛介绍并对数据进行了解释。危险监测区域是石灰岩悬崖上的一个高悬洞穴，其部分洞顶已经坍塌。在洞顶上，有一根不稳定的梁。一条从东向西变薄的水平夹层，在西侧悬挂于洞穴顶部，在东侧夹于岩体中，界定了这根剩余的梁。在梁的周围可以观察到张开的裂缝。为了评估剩余的危险，在洞穴顶部安装了四个测缝计（F1至F4）和一个热探头，并在洞穴上方垂直于悬崖面钻了两个钻孔引伸计（D1和D2），以了解岩体的整体行为。通过因瓦线测量在嵌入岩体的插座之间进行测量。在洞穴内部安装了四个由两个插座组成的基座，在洞穴外部和上方的悬崖面上放置了五个。测量时间从2011年1月持续到2021年6月。测量中观察到有1.5年的间隔，因为在洞穴进行加固工程以保护村庄时，测量暂时停止了。因此，数据集提供了11多年来在悬崖上及内部记录的温度和位移数据，有助于深入了解气候与岩体内部变形之间的关系。这个数据集很新颖，一方面是因为这类数据在文献中不易获得，另一方面是因为它不仅记录了温度和孔径的表面变化，还监测了岩体内部温度和变形的变化。研究人员可以利用这些数据更好地理解岩石中的热机械耦合。他们可以测试自己的模型，特别是关于裂纹扩展或热疲劳的本构定律。
