Special Issue Information

Dear Colleagues,

Geologic hazards such as landslides, rockfalls, debris flows, and earthquakes have presented many engineering geology and geotechnical challenges in the design, building, and maintenance of mountainous infrastructures in recent decades. As a result, the investigations of geologic hazards have gained much attention in the geosciences field, due to their likelihood of causing human casualties and severe economic damage. The activity of geologic hazards and the rough terrain may limit or preclude the collection of geological data necessary to characterize geologic hazards when traditional survey methods are employed. The study of geologic hazards has advanced significantly as a result of the rapid development of remote sensing and GIS technologies. Multi-sensor, multi-platform, and multi-temporal datasets and techniques can improve the quality and quantity of remotely sensed data, allowing us to better understand the behavior and geomorphic evolution of geologic hazards. However, it has been challenging to successfully develop effective early identification and warning systems for geological hazards. Therefore, carrying out a risk assessment and stability analysis for geologic hazards has important theoretical significance and application value, contributing to the establishment of an early warning system and implementing control measures for geologic hazards. This Special Issue aims to showcase the advances in the application of state-of-the-art remote sensing techniques, numerical modeling approaches, and their combination for the characterization, monitoring, simulation, and risk assessment of geologic hazards in different environments. Potential topics include but are not limited to the following:

  • Spatiotemporal analysis of geologic hazards;
  • Field investigations, descriptions, and formation mechanism analysis of geologic hazards;
  • Applications of state-of-the-art remote sensing techniques in geologic hazards;
  • Risk assessment methods for geologic hazards on a regional scale;
  • Applications of advanced Earth observation technologies in geologic hazards;
  • In-depth controlling factor analysis of geologic hazards;
  • Construction of early warning system and reinforcement measures for geologic hazards;
  • New techniques and materials for disaster risk reduction.

Numerous landslides occur in waste dumps due to unscientific placement. The behavior of waste dumps with different material layouts has yet to be understood when it comes to deformation and failure. In this research, several tests of base friction were carried out on mine waste dumps by considering various material layouts under self-weight loading conditions. The waste dump’s displacement was detected by the system composed with image-capture equipment. The findings indicate that the layout of waste materials greatly affected the way a waste dump fails and could be categorized into three types: crest-arced slip, bottom-arced slip, and composite overall slip. Sliding failure caused a gradual development of the slip surface from the dominant fine-gravel material stage to the adjacent waste dump stage. Three phases can be assigned to the waste dump’s failure process: the constant deformation phase, strain localization phase, and failed phase. The layout of waste materials exerts a significant influence on the moment that the waste dump’s deformation enters the three phases. The waste dump’s failure mechanism was explained by describing how maximum shear and volumetric strain developed and transmitted. To determine the most dominant impact during the tests by analyzing the relative degree of volumetric and shear influences on the waste dump, an effect coefficient was proposed. The stability of the waste dump was illustrated and comparatively analyzed based on a simplified approach, in which the moments of initial cracking and local failure were used as a failure index for the model tests. The design and stability analysis of mine waste dumps is strengthened by this study’s strong support, thereby minimizing the risk of landslides and promoting the sustainability of the mining industry.

To proactively respond to the national fourteenth Five-Year Plan policy, we will adhere to a comprehensive land and sea planning approach, working together to promote marine ecological protection, optimize geological space, and integrate the marine economy. This paper provides a comprehensive review of the sustainable development of marine geological hazards (MGHs), with a particular focus on submarine landslides, the marine environment, as well as the marine economy. First, the novelty of this study lies in its review and summary of the temporal and spatial distribution, systematic classification, inducible factors, and realistic characteristics of submarine landslides to enrich the theoretical concept. Moreover, the costs, risks, and impacts on the marine environment and economy of submarine engineering activities such as oil and gas fields, as well as metal ores, were systematically discussed. Combined with the current marine policy, an analysis was conducted on the environmental pollution and economic losses caused by submarine landslides. Herein, the key finding is that China and Mexico are viable candidates for the future large-scale offshore exploitation of oil, gas, nickel, cobalt, cuprum, manganese, and other mineral resources. Compared to land-based mining, deep-sea mining offers superior economic and environmental advantages. Finally, it is suggested that physical model tests and numerical simulation techniques are effective means for investigating the triggering mechanism of submarine landslides, their evolutionary movement process, and the impact on the submarine infrastructure. In the future, the establishment of a multi-level and multi-dimensional monitoring chain for submarine landslide disasters, as well as joint risk assessment, prediction, and early warning systems, can effectively mitigate the occurrence of submarine landslide disasters and promote the sustainable development of the marine environment and economy.

Long-term ground subsidence (LTGS) is a relatively slow process. However, the accumulation of long-term subsidence has an adverse impact on the normal operation and safety of a subway, hindering sustainable urban development. A wide gap exists between early warning theory and its application in the control of LTGS during subway operation due to time span limitation. Providing decision support for LTGS in high-density urban areas during subway operation is difficult, and a collaborative decision system for real-time early warning and intelligent control is currently lacking. This study establishes the functional components of an intelligent early warning and decision platform, proposes a software system module, constructs an overall software framework structure, and develops a mobile intelligent early warning and decision platform. Moreover, this study introduces an early warning method for LTGS in high-density urban areas during subway operation. This method integrates an intelligent early warning decision-making platform, namely Differential Synthetic Aperture Radar Interferometry (DInSAR), land subsidence monitoring, operation tunnel subsidence monitoring, and other multisource data coupling. The method is applied to sections of the Hangzhou Metro Line 4 Phase I Project (Chengxing Road Station (CRS)–Civic Center Station (CCS)–Jiangjin Road Station (JRS) and Xinfeng Station (XS)–East Railway Station (ERS)–Pengbu Station (PS)). This work can serve as a reference for ensuring urban safety and promoting sustainable development. Full article
