“…External drivers in practical engineering are more complex. For instance, driven by rainfall, earthquakes, and human activities, changes in temperature fields may trigger geological hazards (Roje-Bonacci et al, 2009;Ma J et al, 2018;Oswald et al, 2021;Li et al, 2022). Several studies have indicated that geological hazards such as earthquakes exhibit critical slowing phenomena (Qiao et al, 2022).…”

The critical point of rock mass transition from stable to unstable states is significant for the prevention and control of rock engineering hazards. This study explored the precursor characteristics of instability in sandstone containing prefabricated fractures and intact sandstone based on the critical slowing down (CSD) theory. The results demonstrated that as the input energy drove the dissipation energy dynamic system toward the critical point of two states, the CSD phenomenon appeared, which was manifested by the sudden increase in CSD time series metrics (skewness, kurtosis, and coefficient of variation) and autoregressive model metrics (variance and autocorrelation coefficient). The CSD characteristics of different dissipation energy dynamical systems were different, resulting in different times of CSD phenomena for distinct systems. In addition, the angle of the sandstone fracture affected the characteristics of the dissipation energy dynamical system and hence the appearance time of the precursor information. The precursor time of the sandstone containing 45° parallel fractures appeared earliest among all rock samples, and the ratio of the appearance time of the precursor point to the failure time of all rock samples reached more than 80%, which had good timeliness. The stress at the precursor point reached more than 80% of the peak stress, which corresponded to the plastic stage in the loading process, indicating that the CSD indicators constitute an effective monitoring index, which can provide an important reference for the stability monitoring and early warning of the field rock project.

“…High temperatures lead to the drainage of the surface area of the terrain, creating larger cracks, which after the first rainfalls absorb the water and degrade the structure of the surface sediments. This is more characteristic to the mountainous or slightly aslope terrains, which leads to disturbance of natural environmental balance and activation of rock mass, resulting in a formation of landslides of a certain scale [1,2,3,4,5,6,7,8,9]. Construction of facilities often results in a disturbance of terrain stability at all weather seasons during the year, depending from the degree of its natural stability.…”

The Republic of Srpska, which is an integral part of Bosnia and Herzegovina, was affected by intenseprecipitation during May 2014 and May 2015. The northern part of the Republic of Srpska is locatedbetween the plain area of the Sava River and the mountain massif of the inner Dinarides, while theeastern and western parts are confined to the rivers Drina and Una. Increased precipitation, which in2014 was three times higher than the average, activated large number of landslides, and most of themthreatened the facilities of various purposes. One year later, in the same month, this area was again hitby intense precipitation, less than in the previous year, but more significant by the size of activatedlandslides.The most significant landslides were formed along the roads, and the degree of damage is different,depending on the method of construction and maintenance during exploitation.The slopes on whichroads are built are in general conditionally stable, and for years have kept their stability in naturalconditions. By engineering interventions during the construction of the roads, the natural state ofbalance was disturbed, which was manifested with delay, since the slopes were not well repaired. Theopen terrain profiles on the slopes created favorable conditions for water to flow into the quasihomogeneous and heterogeneous clay sediments, where their stability was disturbed.The roads that were built of good quality as well as slope reparations during construction did not havesignificant damage during intense precipitation, although some of them were built several decadesearlier. During the inventory of landslides on the roads, the effects of elemental and anthropogenicprocesses were analyzed, where 23 of the characteristic landslides were selected. The periods ofconstruction before and after 1990 were separated, that is, the periods of earlier quality construction offacilities from today's modern one.
