Background

The field of geotechnical engineering has long recognized the critical role of water-rock interactions in influencing the mechanical behavior of rock masses, particularly in the context of mining and civil engineering applications. Recent studies have focused on the dynamic behavior of rocks in deep geological environments, which is crucial for the safe and sustainable extraction of coal, non-ferrous metals, and other minerals, as well as for the construction of engineering projects such as tunnels. Studies have employed various experimental setups, including the split Hopkinson pressure bar (SHPB), true-triaxial low-frequency disturbance devices, and conventional static compression testing equipment, to delve into the mechanical properties and disaster mechanisms of rocks under diverse dynamic and static loads. These experiments have revealed significant insights into the strength changes, vibration characteristics, and deformation behaviors of rocks subjected to dynamic disturbances. However, despite these achievements, there is a need for further investigation into the deformation and destabilization mechanisms of water-rich rock masses under dynamic disturbances, particularly the impact of the coupled effects of water content and strain rate on rock strength, energy evolution, and rockburst propensity. The complex interplay between water content and dynamic loads continues to pose challenges in predicting rock strength, assessing the stability of surrounding rock, and preventing engineering hazards such as rock bursts and collapse.

This Research Topic aims to deepen our understanding of the dynamic responses of water-saturated rocks under various loading conditions, and to elucidate the mechanisms driving their deformation, failure, and acoustic emission behaviors. By exploring the water-rock coupling effects in dynamic environments, the goal is to develop more accurate predictive models and effective mitigation strategies for geotechnical engineering disasters. The research will also investigate the impact of water content on the mechanical properties of rocks, the evolution of microcracks, and the degradation mechanisms under wetting-drying cycles, with a focus on improving the safety and efficiency of underground engineering projects.
To gather further insights in the complex interactions between water and rock materials under dynamic loading conditions, we welcome articles addressing, but not limited to, the following themes:

- Coupled effects of water and strain rate on the mechanical behavior of rocks
- Mechanism of rockburst under varying water or dynamic conditions
- Strengthening or retarding effect of groundwater on rock dynamic failure in different structural environments
- Energy evolution and strength characteristics of water-bearing rocks in dynamic environment
- Mathematical model of mechanics response of rock under water and dynamic disturbance conditions
- Rock failure criteria considering water or dynamic disturbance conditions
- Numerical modeling and simulation of rock failure under various water or dynamic disturbance conditions
- Multi-scale effects of water-rock reactions
- Acoustic emission characteristics and their correlation with rock deformation and failure
- Water driven or dynamic driven mechanisms for microcrack evolution
- Effects of wetting-drying cycles or dynamic load cycles on the mechanical behavior of rocks

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

      In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
