Tunnels are important infrastructures, but faults and internal water pressure can reduce their seismic performance. These risks are relevant in seismic regions including Indonesia. Although finite element methods are used to analyze tunnel behavior, models with continuous linings overestimate stresses, while the influence of segmental joints remains underexplored. This study investigates the seismic response of the Bener Dam diversion tunnel, Central Java, Indonesia, which crosses an inactive fault and uses segmental lining, using nonlinear time-history finite element analysis. Three scenarios were analyzed: presence versus absence of a fault, empty versus water-filled conditions, and continuous versus jointed linings. The results indicated that fault-crossing tunnels are most vulnerable to horizontal slip, especially under pulse-like earthquakes, with strains concentrated near faults. Water minimally affects deformation but increases internal stress, while segmental joints elevate peak strain yet localize damage. These findings highlighted the need to consider fault, water, and joint effects in seismic tunnel design.
Segmental column–supported bridges (SCSBs) are being adopted more widely in the construction industry owing to their various benefits, e.g., better quality control, shorter construction time, less environmental impact, and smaller residual displacement. With the growing applications of SCSBs, they are more likely to...

Currently, a large number of post-earthquake surveys and statistical analyses of tunnel damage indicate that tunnels built against mountainsides are subject to the coupled effects of “asymmetric loads and seismic cyclic action,” which increase the risk of earthquake-induced damage to these tunnels. Therefore, the pri...
The seismic safety of high core rockfill dams has always been one of the core issues in water conservancy construction, especially in the dam crest area where significant seismic response, known as the “whip effect”, occurs under strong earthquake action. It is necessary to pay special attention to the seismic performa...

Developing geoenergy technologies such as Enhanced Geothermal Systems (EGS) requires underground fluid injection operations, which, under certain conditions, can induce large-magnitude earthquakes. To mitigate the seismic hazard, various injection protocols have been proposed to regulate operational parameters. This st...

The M7.9 Myanmar earthquake on March 28, 2025, caused extensive damage to the local transportation network. Through a 14‐day field investigation in the affected areas, a joint Sino–Myanmar survey team established a seismic damage database encompassing highway and railway bridges. To address the scarcity of near‐fault s...
