Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Dizhen xuebao, 2022 以典型的两层三跨形式地铁车站为研究对象，采用非线性动力时程反应分析方法，对软土场地的地铁车站与上部交叉桥梁模型进行数值模拟分析，给出了一种潜在的地铁车站−桥梁耦联破坏模式，分析了地铁车站与上部桥梁的地震动力相互作用。数值模拟结果表明：桥梁对车站的地震响应影响较小，车站发生破坏主要取决于地震作用及其本身的强度；地铁车站发生破坏后会引起邻近区域土层产生较大的水平和竖向变形，进而会引起邻近区域地基失效并使桥梁发生落梁破坏；地铁车站遭地震破坏后，桥梁基础带动邻近区域的土层整体向车站方向移动，加剧车站坍塌震害。

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.
