“…This has brought about the current status of herdsmen's housing and housing needs, causing the unique nomadic civilized life to face a crisis of elimination. However, the current research efforts on yurts are mostly focused on space [3,4], physical environment [5,6], structure and materials [7], cultural implications, inheritance and development [8], and optimization design [9][10][11].…”

The residential Mongolian yurt is representative of nomadic culture and its mobile residences. Behavior forms the closest connection the environment and people. There is almost no research about the residence and lifestyle of Mongolian yurt dwellers from the perspective of housing behavior. This study applied grounded theoretical methods to analyze the theoretical model of the influence mechanism of Mongolian yurt dwelling on behavior. Interviews were conducted according to the principle of purposive sampling, and were summarized in five categories: production lifestyle, natural environment, residential characteristics, cultural beliefs, and emotional experience. Production lifestyle is the core category and the critical factor in dwelling behavior, which interacts with the other main categories. Pastoral policy is the factor that has worked most quickly and directly to influence housing in yurts. Mongolians living in yurts on the prairie show higher satisfaction compared to those in urban housing, which is related to the Mongolian advocacy for nature and freedom.

“…Besides, on-site monitoring can well reflect the dynamic changes in excavation engineering and the working state of surrounding rock and support (Kavvadas, 2005;Masini et al, 2021). Therefore, researchers have also strived to explain the accident mechanism based on on-site monitoring data such as surface deformation (Liu F. et al, 2022;Wang et al, 2022c), lining stress (Chen B. et al, 2022), water inflow (Liu et al, 2021;Liu J. et al, 2022), and microseismic signal (Cheng et al, 2018;Liu et al, 2019). Previous studies have provided valuable insights into the correlation between disasters and factors such as strata, groundwater, and support, particularly concerning deformation, stress, and strain (Liang et al, 2014;Chen L. et al, 2022;Feng et al, 2022;Li et al, 2023).…”

The tunnel collapse occurred during the construction of the Qingdao Metro Line Ⅰ, resulting in a pit measuring approximately 10 m in diameter and 7 m in depth on the ground surface. The collapse inflicted substantial economic losses, casualties, and subsequent disruptions to ongoing construction activities. To clarify the causes of this collapse and investigate the underlying factors, a comprehensive approach combining field surveys and numerical simulations was undertaken. The results show that the collapse was primarily attributed to inadequate support when facing the challenging geological conditions, poor surrounding rocks (Grade VI) and a high volume of groundwater. The combination of abundant water and sand seeped into the tunnel, culminating in a catastrophic ground collapse. Notably, the arch roof experienced extensive deformation and damage due to the significant seepage pressure, which was exacerbated by the absence of timely support. Then, ground grouting was promptly conducted to repair the affected area and reinforce the tunnel structure. Subsequent monitoring of surface deformations following the resumption of tunneling operations indicated the effectiveness of the disaster treatment approach. These achievements constitute a reliable theoretical foundation for similar projects, particularly in terms of environmental protection and ensuring safe construction practices.

“…Zhang et al (2020) quantitatively analyzed the peak strength, effective elastic modulus, and related failure characteristics of fractured marble using the discrete element method and numerical experiments. Liu et al (2019), Liu et al (2022) studied the progressive failure process of surrounding rock using field microseismic (MS) monitoring technology and provided a method for predicting collapse. Zhou et al (2021a) studied the stability of the crown pillar from induced microseismicity and that it is helpful for the characterization of seepage channel development.…”

Collapse is one of the most frequent geological disasters in mountain tunnel engineering, posing major safety concerns for underground structures and construction crews. According to a catastrophic collapse in the shallow buried area of the Huangjiakuang tunnel in Weihai City, Shandong Province, the contributing factors, that is, the surrounding rock property, influence of neighboring tunnel construction, and tunnel over-excavation are systematically investigated. The tunnel collapse, breaks through the ground surface, is inverted using MIDAS GTS NX. A tunnel deformation analysis model is created using the quantitative methods of grey relation analysis and entropy weight methods based on crown settlement and lateral wall horizontal contraction during tunnel excavation. The surrounding rock property, the distance between the left and right tunnel faces, and the over-excavation height have a significant effect on tunnel deformation, which are quantitatively interpreted using the tunnel deformation analysis model. This study is valuable for the multi-factor analysis of tunnel deformation and determining the main contributing factors to the collapse quantitatively.
