Seismic Fragility of Gravity and Semi‐Gravity Retaining Walls and Its Impact on the Functionality Loss of Road Infrastructures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls are key geotechnical components of road infrastructure, whose seismic performance directly affects the resilience of transportation networks. Despite their importance, seismic fragility models for retaining walls available in the literature refer only to specific case studies.

Mechanisms of Roadway Instability and Coupled Control Technology for Working Face Passing Through Fault Zones

Energy Science &Engineering, EarlyView.
This study mainly explores the instability characteristics of roadways near faults in the working face. Taking the 51104 transportation roadway of the 51104 working face in Shengxin Coal Mine as the main research object, through theoretical analysis, borehole inspection, numerical simulation and on‐site mine pressure observation, the instability ...

Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

Energy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Experimental Analysis of Vibration Transfer Characteristics of an Elevated Railroad Station

Journal of The Korean Society of Disaster Information, 2015
선하역사 내부에 발생하는 소음을 저감하기 위해서는 진동의 감소가 필요하며, 보다 효 과적인 진동 저감 대책 수립을 위해서는 궤도-접속교량-구조물의 상호작용 특성을 감안 하여 열차 운행으로 발생하는 진동이 전달되는 경로 및 특성에 대한 명확한 이해가 필 요하다. 이 논문에서는 국내 선하역사 현황을 구조적으로 분류하고 대표 선하역사에 대 한 진동 측정을 통하여 역사에 발생하는 진동의 전달 특성을 분석하였다. 주파수응답을 통한 분석 결과 궤도의 진동이 역사로 전달되면서 고주파 성분이 큰 감소를 나타냈으 며, 일부 역사에서 저주파 대역 내 증폭 구간이 발견되었다. 플로팅궤도가 적용되거나 TPS 구조의 역사는 궤도로부터 전달되는 진동이

Designing a Culture‐Driven C‐STEAM Project Framework for Vocational Education

Future in Educational Research, EarlyView.
ABSTRACT Amid rapid technological advances and a growing emphasis on cultural sustainability in education, STEAM education has been widely adopted to support interdisciplinary learning and decision‐making skills. However, many STEAM implementations remain largely instrumental, regularly neglecting cultural meaning‐making, value orientation, and ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Rethinking a positive‐sum game: US FDI location decisions in the presence of Chinese FDI

Global Strategy Journal, EarlyView.
Abstract Research Summary This study examines how rising Chinese outbound foreign direct investment (OFDI) in third‐country markets shapes US MNEs' foreign direct investment location decisions amid escalating US–China geopolitical rivalry. US firms initially benefit from complementary co‐location dynamics, as Chinese OFDI—particularly in infrastructure—
