关键词：Twoyear growth of Deep Underground Science and Engineering A perspective
摘要：Deep Underground Science and Engineering (DUSE) launched its first issue in September 2022 as a quarterly journal. So far, it has published 106 articles with nine issues and online early view. The volume of received manuscripts increases by 50% each year and over 200 manuscripts were received by 28th of November 2024. In the early period, DUSE authorship came from five countries and now reaches...

摘要：边坡的表面侵蚀是自然和工程环境中常见的地质过程，通常由降雨、河流或地下水的影响引发，导致土壤和岩石表面层逐渐侵蚀或冲刷。初始侵蚀会逐渐演变为浅层滑坡，并进一步发展为深层滑坡。随着降雨越来越多地触发隧道和边坡的表面侵蚀，从初始侵蚀到深层滑坡的进程成为一个日益关注的问题。该研究可为分析隧道-边坡系统的地表水土流失提供参考。

关键词：The influence of the disturbing effect roadways through faults on stability and slip characteristics
摘要：AbstractIn order to mitigate the risk of geological disasters induced by fault activation when roadways intersect reverse faults in coal mining, this paper uses a combination of mechanical models with PFC2D software. A mechanical model is introduced to represent various fault angles, followed by a series of PFC2D loading and unloading tests to validate the model and investigate fault instabilit...

关键词：Prediction of rock mass classification in tunnel boring machine tunneling using the principal component analysis PCAgated recurrent unit GRU neural network
摘要：AbstractDue to the complexity of underground engineering geology, the tunnel boring machine (TBM) usually shows poor adaptability to the surrounding rock mass, leading to machine jamming and geological hazards. For the TBM project of Lanzhou Water Source Construction, this study proposed a neural network called PCA–GRU, which combines principal component analysis (PCA) with gated recurrent uni...

关键词：Research on the bearing capacity characteristics of initial support for horseshoeshaped tunnel prefabrication
摘要：AbstractIn view of the limited theoretical research on the load model of initial support for horseshoe-shaped prefabrication, this study focuses on the Luochuan Tunnel on the Xi'an-Yan'an newly built railway as the research object to explore its load model, load characteristic curve, plastic zone, deformation, and critical thickness. Theoretical research and numerical analysis were conducted. T...
