“…In fact, surrounding rock suffers freeze-thaw cycles and deteriorates during the operation stage of cold region tunnels. Ding et al (2020) investigated the deterioration in mechanical properties with freeze-thaw cycles in a tight sandstone and studied changes to its pore structure using nuclear magnetic resonance technology. Huang et al (2022a, b) studied the pore structure change of red sandstone under freeze-thaw cycles by mercury intrusion porosimetry and found that both the uniaxial compressive strength and the triaxial compressive strength decrease due to the growth of macropores.…”

During the operation stage of cold region tunnels, the isotropic surrounding rock in a freeze–thaw circle suffers long-term unidirectional freeze–thaw cycles and gradually transforms into transversely isotropic material, which induces the variation of stress and displacement distribution of cold region tunnels. Aimed at this phenomenon, an analytical solution of mechanical response in cold region tunnels under transversely isotropic freeze–thaw circles induced by unidirectional freeze–thaw damage is proposed. The analytical solution is derived under two different states of the freeze–thaw circle: 1) transversely isotropic and unfrozen state (state TU) and 2) transversely isotropic and frozen state (state TF). In addition, the stress distribution in the lining and surrounding rock with a transversely isotropic freeze–thaw circle is analyzed. The transformation of the surrounding rock in a freeze–thaw circle from isotropic material into transversely isotropic material leads to the increase of stress in the lining, especially for a significant increase under state TF. Finally, the influence of the deterioration coefficient and the degree of anisotropy on the stress distribution in the lining is analyzed. The stress in the lining increases linearly as the deterioration coefficient decreases, while it increases nonlinearly as the degree of anisotropy decreases. The smaller the degree of anisotropy is, the greater the increase rate of the stress is. Moreover, the increase of stress with deterioration coefficient and degree of anisotropy under state TF is much greater than that under state TU. Both deterioration coefficient and degree of anisotropy decrease from 1.0 with increasing unidirectional freeze–thaw cycles suffered by surrounding rock, and, thus, induce the increase of stresses in the lining. In addition, the deterioration coefficient has a greater influence than the degree of anisotropy on the stress in the lining.

“…At present, the study of rock mechanics in cold regions has gradually become one of the hot topics, and the application of new technologies and means promotes its development, such as Nuclear Magnetic Resonance (NMR) technology (Ding et al 2020;Zhou et al 2015;Liu et al 2021;Jia et al 2020;Liu et al 2020a;Pan et al 2020;Zhang et al 2020d;Liu et al 2020b;), Ultrasonic Detections (Ding et al 2020;Wang et al 2017;Çelik, 2020;Wang et al 2019;Ivankina et al 2020), Digital Image Correlation (DIC) (Mardoukhi et al 2021), Neutron Diffraction Measurements (Ivankina et al 2020), Scanning Electron Microscope (SEM) (Wang et al 2017;Çelik, 2020;Wang et al 2019;Chang et al 2020;Abdolghanizadeh et al 2020;Fang et al 2018;Zhou et al 2018;Yang et al 2021b;Zhou et al 2019;Zhao et al 2019), Computed Tomography (CT) technique (Wang et al 2020b), Optical Microscope (Çelik, 2020;Mousavi et al 2020), X-ray Computed Micro-tomography (Deprez et al 2020b), X-ray diffraction (XRD) (Zhao et al 2019;Mousavi et al 2020), Acoustic Emission (Wang et al 2020b;Xiao et al 2020), Infrared thermography (Yang et al 2021a).

The mechanics of rock masses in cold regions have attracted the attention of researchers from all over the world, and the concern here is that the mechanical properties of rock masses are inevitably weakened under freeze-thaw cycles. In this paper, firstly, granite samples were subjected to different freeze-thaw cycles, after that, we dealt with the freeze-thawed samples considering four different states, such as saturated and frozen states, saturated and normal temperature states, dry and frozen states as well as dry and normal temperature states. The impact compression test was carried out by using the Split Hopkinson Pressure Bar (SHPB) device. Results show that the impact strength of granite samples deteriorates with the increase of freeze-thaw cycles in the same state, for samples in different states, although the number of freeze-thaw cycles is equal, the degree of deterioration of the impact strength is different. For freeze-thawed granite samples in the same state, the dynamic elastic modulus decreases with the increase of freeze-thaw cycles, and its degree of decrease is different for different states. Under the same freeze-thaw cycles, the deterioration of mechanical properties of granite samples is different in four different weather states, for example, the dynamic elastic modulus from large to small is generally as follows: saturated and frozen states, saturated and normal temperature states, dry and frozen states as well as dry and normal temperature states. Finally, the freeze-thaw influence factor is proposed to describe the damage of granite samples. All in all, it can be concluded that water and low temperature strengthen the influence of freeze-thaw cycles on the dynamic mechanical properties of granite samples.

“…In Europe, on the other hand, several examples on characterization of physical and mechanical characteristics of construction materials can be mentioned: dry stone heritage materials and limestone from Portugal [ 19 , 20 ], freshwater limestones used in Bosnia and Herzegovina [ 21 ] and limestones from Italy [ 22 ]. Techniques involve on-site testing [ 23 ] and adoption of non-destruction techniques [ 24 , 25 ].…”

Physical-Mechanical Properties of Stone Masonry of Gjirokastër, Albania

In addition to reinforced concrete and steel buildings, a large part of the existing building stock in Europe is made of stone masonry. Prediction of the structural behavior requires the development of a systematic material characterization of the mechanical properties and structural details (units, arrangement, bonding, inter-connection). This study aims to analyze the mechanical and physical behavior of building stones in the historical city of Gjirokastër, Albania, known also as the Stone City. A thorough investigation of the regional stone quarries was performed, and the collected samples were cut into regular prismatic specimens for further analysis. The experimental campaign consisted of the determination of flexural strength and compressive strength, water absorption, porosity, specific gravity as well as structural analysis of the masonry material, using the MQI (Masonry Quality Index) method. The test results showed that there is a large scattering in the values of the mechanical and physical stone properties such as compressive strength varying from 20 to 115 MPa and flexural strength from 8 to 25 MPa. However, the analysis of the masonry material revealed a satisfactory structural performance, based on a frequent, systematic respect of the good construction practices (i.e., the rules of the art) in Gjirokastër.
