Abstract

Critical nodes in transportation networks, such as major transit tunnels and interchange stations, are vital for maintaining system functionality following a disruptive event such as a large earthquake. This study evaluates the seismic resilience of BART’s Berkeley Hills Tunnel that passes through the Hayward Fault, which is a high-activity strike-slip fault. The Hayward Fault poses a significant risk, with the potential for a magnitude 7 + earthquake that could severely impact the tunnel, potentially disrupting BART service and affecting the broader transit network. Considering a probabilistic distribution of fault rupture displacements, we assess the resulting tunnel damage. We also evaluate the likelihood of service interruptions caused by potential Hayward Fault events. The results indicate that the tunnels may experience minor to significant damage depending on the amplitude of the fault displacement, which can lead to repair times ranging from a few weeks to over a year.

BART伯克利山隧道对断层位移的响应及其对系统功能的影响

交通网络中的关键节点，如主要的交通隧道和换乘站，对于在大地震等破坏性事件发生后维持系统功能至关重要。本研究评估了BART的伯克利山隧道穿过海沃德断层的抗震能力，这是一个高活动性的走滑断层。海沃德断层带来了巨大的风险，有可能发生7级以上的地震，这可能会严重影响隧道，潜在地中断BART服务，并影响更广泛的交通网络。考虑断层破裂位移的概率分布，评估由此产生的隧道损伤。我们还评估了潜在的海沃德故障事件导致服务中断的可能性。结果表明，根据断层位移的幅度，隧道可能会遭受轻微到严重的破坏，这可能导致修复时间从几周到一年多不等。

期刊介绍： Tunnelling and Underground Space Technology is an international journal which publishes authoritative articles encompassing the development of innovative uses of underground space and the results of high quality research into improved, more cost-effective techniques for the planning, geo-investigation, design, construction, operation and maintenance of underground and earth-sheltered structures. The journal provides an effective vehicle for the improved worldwide exchange of information on developments in underground technology - and the experience gained from its use - and is strongly committed to publishing papers on the interdisciplinary aspects of creating, planning, and regulating underground space.
